Hadoop Cloud Scripts
|
||||
====================
|
||||
|
||||
These scripts allow you to run Hadoop on cloud providers. These instructions
|
||||
assume you are running on Amazon EC2, the differences for other providers are
|
||||
noted at the end of this document.
|
||||
|
||||
Getting Started
|
||||
===============
|
||||
|
||||
First, unpack the scripts on your system. For convenience, you may like to put
|
||||
the top-level directory on your path.
|
||||
|
||||
You'll also need python (version 2.5 or newer) and the boto and simplejson
|
||||
libraries. After you download boto and simplejson, you can install each in turn
|
||||
by running the following in the directory where you unpacked the distribution:
|
||||
|
||||
% sudo python setup.py install
|
||||
|
||||
Alternatively, you might like to use the python-boto and python-simplejson RPM
|
||||
and Debian packages.
|
||||
|
||||
You need to tell the scripts your AWS credentials. The simplest way to do this
|
||||
is to set the environment variables (but see
|
||||
http://code.google.com/p/boto/wiki/BotoConfig for other options):
|
||||
|
||||
* AWS_ACCESS_KEY_ID - Your AWS Access Key ID
|
||||
* AWS_SECRET_ACCESS_KEY - Your AWS Secret Access Key
|
||||
|
||||
To configure the scripts, create a directory called .hadoop-cloud (note the
|
||||
leading ".") in your home directory. In it, create a file called
|
||||
clusters.cfg with a section for each cluster you want to control. e.g.:
|
||||
|
||||
[my-hadoop-cluster]
|
||||
image_id=ami-6159bf08
|
||||
instance_type=c1.medium
|
||||
key_name=tom
|
||||
availability_zone=us-east-1c
|
||||
private_key=PATH_TO_PRIVATE_KEY
|
||||
ssh_options=-i %(private_key)s -o StrictHostKeyChecking=no
|
||||
|
||||
The image chosen here is one with a i386 Fedora OS. For a list of suitable AMIs
|
||||
see http://wiki.apache.org/hadoop/AmazonEC2.
|
||||
|
||||
The architecture must be compatible with the instance type. For m1.small and
|
||||
c1.medium instances use the i386 AMIs, while for m1.large, m1.xlarge, and
|
||||
c1.xlarge instances use the x86_64 AMIs. One of the high CPU instances
|
||||
(c1.medium or c1.xlarge) is recommended.
|
||||
|
||||
Then you can run the hadoop-ec2 script. It will display usage instructions when
|
||||
invoked without arguments.
|
||||
|
||||
You can test that it can connect to AWS by typing:
|
||||
|
||||
% hadoop-ec2 list
|
||||
|
||||
LAUNCHING A CLUSTER
|
||||
===================
|
||||
|
||||
To launch a cluster called "my-hadoop-cluster" with 10 worker (slave) nodes
|
||||
type:
|
||||
|
||||
% hadoop-ec2 launch-cluster my-hadoop-cluster 10
|
||||
|
||||
This will boot the master node and 10 worker nodes. The master node runs the
|
||||
namenode, secondary namenode, and jobtracker, and each worker node runs a
|
||||
datanode and a tasktracker. Equivalently the cluster could be launched as:
|
||||
|
||||
% hadoop-ec2 launch-cluster my-hadoop-cluster 1 nn,snn,jt 10 dn,tt
|
||||
|
||||
Note that using this notation you can launch a split namenode/jobtracker cluster
|
||||
|
||||
% hadoop-ec2 launch-cluster my-hadoop-cluster 1 nn,snn 1 jt 10 dn,tt
|
||||
|
||||
When the nodes have started and the Hadoop cluster has come up, the console will
|
||||
display a message like
|
||||
|
||||
Browse the cluster at http://ec2-xxx-xxx-xxx-xxx.compute-1.amazonaws.com/
|
||||
|
||||
You can access Hadoop's web UI by visiting this URL. By default, port 80 is
|
||||
opened for access from your client machine. You may change the firewall settings
|
||||
(to allow access from a network, rather than just a single machine, for example)
|
||||
by using the Amazon EC2 command line tools, or by using a tool like Elastic Fox.
|
||||
There is a security group for each node's role. The one for the namenode
|
||||
is <cluster-name>-nn, for example.
|
||||
|
||||
For security reasons, traffic from the network your client is running on is
|
||||
proxied through the master node of the cluster using an SSH tunnel (a SOCKS
|
||||
proxy on port 6666). To set up the proxy run the following command:
|
||||
|
||||
% hadoop-ec2 proxy my-hadoop-cluster
|
||||
|
||||
Web browsers need to be configured to use this proxy too, so you can view pages
|
||||
served by worker nodes in the cluster. The most convenient way to do this is to
|
||||
use a proxy auto-config (PAC) file, such as this one:
|
||||
|
||||
http://apache-hadoop-ec2.s3.amazonaws.com/proxy.pac
|
||||
|
||||
If you are using Firefox, then you may find
|
||||
FoxyProxy useful for managing PAC files. (If you use FoxyProxy, then you need to
|
||||
get it to use the proxy for DNS lookups. To do this, go to Tools -> FoxyProxy ->
|
||||
Options, and then under "Miscellaneous" in the bottom left, choose "Use SOCKS
|
||||
proxy for DNS lookups".)
|
||||
|
||||
PERSISTENT CLUSTERS
|
||||
===================
|
||||
|
||||
Hadoop clusters running on EC2 that use local EC2 storage (the default) will not
|
||||
retain data once the cluster has been terminated. It is possible to use EBS for
|
||||
persistent data, which allows a cluster to be shut down while it is not being
|
||||
used.
|
||||
|
||||
Note: EBS support is a Beta feature.
|
||||
|
||||
First create a new section called "my-ebs-cluster" in the
|
||||
.hadoop-cloud/clusters.cfg file.
|
||||
|
||||
Now we need to create storage for the new cluster. Create a temporary EBS volume
|
||||
of size 100GiB, format it, and save it as a snapshot in S3. This way, we only
|
||||
have to do the formatting once.
|
||||
|
||||
% hadoop-ec2 create-formatted-snapshot my-ebs-cluster 100
|
||||
|
||||
We create storage for a single namenode and for two datanodes. The volumes to
|
||||
create are described in a JSON spec file, which references the snapshot we just
|
||||
created. Here is the contents of a JSON file, called
|
||||
my-ebs-cluster-storage-spec.json:
|
||||
|
||||
{
|
||||
"nn": [
|
||||
{
|
||||
"device": "/dev/sdj",
|
||||
"mount_point": "/ebs1",
|
||||
"size_gb": "100",
|
||||
"snapshot_id": "snap-268e704f"
|
||||
},
|
||||
{
|
||||
"device": "/dev/sdk",
|
||||
"mount_point": "/ebs2",
|
||||
"size_gb": "100",
|
||||
"snapshot_id": "snap-268e704f"
|
||||
}
|
||||
],
|
||||
"dn": [
|
||||
{
|
||||
"device": "/dev/sdj",
|
||||
"mount_point": "/ebs1",
|
||||
"size_gb": "100",
|
||||
"snapshot_id": "snap-268e704f"
|
||||
},
|
||||
{
|
||||
"device": "/dev/sdk",
|
||||
"mount_point": "/ebs2",
|
||||
"size_gb": "100",
|
||||
"snapshot_id": "snap-268e704f"
|
||||
}
|
||||
]
|
||||
}
|
||||
|
||||
|
||||
Each role (here "nn" and "dn") is the key to an array of volume
|
||||
specifications. In this example, the "slave" role has two devices ("/dev/sdj"
|
||||
and "/dev/sdk") with different mount points, sizes, and generated from an EBS
|
||||
snapshot. The snapshot is the formatted snapshot created earlier, so that the
|
||||
volumes we create are pre-formatted. The size of the drives must match the size
|
||||
of the snapshot created earlier.
|
||||
|
||||
Let's create actual volumes using this file.
|
||||
|
||||
% hadoop-ec2 create-storage my-ebs-cluster nn 1 \
|
||||
my-ebs-cluster-storage-spec.json
|
||||
% hadoop-ec2 create-storage my-ebs-cluster dn 2 \
|
||||
my-ebs-cluster-storage-spec.json
|
||||
|
||||
Now let's start the cluster with 2 slave nodes:
|
||||
|
||||
% hadoop-ec2 launch-cluster my-ebs-cluster 2
|
||||
|
||||
Login and run a job which creates some output.
|
||||
|
||||
% hadoop-ec2 login my-ebs-cluster
|
||||
|
||||
# hadoop fs -mkdir input
|
||||
# hadoop fs -put /etc/hadoop/conf/*.xml input
|
||||
# hadoop jar /usr/lib/hadoop/hadoop-*-examples.jar grep input output \
|
||||
'dfs[a-z.]+'
|
||||
|
||||
Look at the output:
|
||||
|
||||
# hadoop fs -cat output/part-00000 | head
|
||||
|
||||
Now let's shutdown the cluster.
|
||||
|
||||
% hadoop-ec2 terminate-cluster my-ebs-cluster
|
||||
|
||||
A little while later we restart the cluster and login.
|
||||
|
||||
% hadoop-ec2 launch-cluster my-ebs-cluster 2
|
||||
% hadoop-ec2 login my-ebs-cluster
|
||||
|
||||
The output from the job we ran before should still be there:
|
||||
|
||||
# hadoop fs -cat output/part-00000 | head
|
||||
|
||||
RUNNING JOBS
|
||||
============
|
||||
|
||||
When you launched the cluster, a hadoop-site.xml file was created in the
|
||||
directory ~/.hadoop-cloud/<cluster-name>. You can use this to connect to the
|
||||
cluster by setting the HADOOP_CONF_DIR enviroment variable (it is also possible
|
||||
to set the configuration file to use by passing it as a -conf option to Hadoop
|
||||
Tools):
|
||||
|
||||
% export HADOOP_CONF_DIR=~/.hadoop-cloud/my-hadoop-cluster
|
||||
|
||||
Let's try browsing HDFS:
|
||||
|
||||
% hadoop fs -ls /
|
||||
|
||||
Running a job is straightforward:
|
||||
|
||||
% hadoop fs -mkdir input # create an input directory
|
||||
% hadoop fs -put $HADOOP_HOME/LICENSE.txt input # copy a file there
|
||||
% hadoop jar $HADOOP_HOME/hadoop-*-examples.jar wordcount input output
|
||||
% hadoop fs -cat output/part-00000 | head
|
||||
|
||||
Of course, these examples assume that you have installed Hadoop on your local
|
||||
machine. It is also possible to launch jobs from within the cluster. First log
|
||||
into the namenode:
|
||||
|
||||
% hadoop-ec2 login my-hadoop-cluster
|
||||
|
||||
Then run a job as before:
|
||||
|
||||
# hadoop fs -mkdir input
|
||||
# hadoop fs -put /etc/hadoop/conf/*.xml input
|
||||
# hadoop jar /usr/lib/hadoop/hadoop-*-examples.jar grep input output 'dfs[a-z.]+'
|
||||
# hadoop fs -cat output/part-00000 | head
|
||||
|
||||
TERMINATING A CLUSTER
|
||||
=====================
|
||||
|
||||
When you've finished with your cluster you can stop it with the following
|
||||
command.
|
||||
|
||||
NOTE: ALL DATA WILL BE LOST UNLESS YOU ARE USING EBS!
|
||||
|
||||
% hadoop-ec2 terminate-cluster my-hadoop-cluster
|
||||
|
||||
You can then delete the EC2 security groups with:
|
||||
|
||||
% hadoop-ec2 delete-cluster my-hadoop-cluster
|
||||
|
||||
AUTOMATIC CLUSTER SHUTDOWN
|
||||
==========================
|
||||
|
||||
You may use the --auto-shutdown option to automatically terminate a cluster
|
||||
a given time (specified in minutes) after launch. This is useful for short-lived
|
||||
clusters where the jobs complete in a known amount of time.
|
||||
|
||||
If you want to cancel the automatic shutdown, then run
|
||||
|
||||
% hadoop-ec2 exec my-hadoop-cluster shutdown -c
|
||||
% hadoop-ec2 update-slaves-file my-hadoop-cluster
|
||||
% hadoop-ec2 exec my-hadoop-cluster /usr/lib/hadoop/bin/slaves.sh shutdown -c
|
||||
|
||||
CONFIGURATION NOTES
|
||||
===================
|
||||
|
||||
It is possible to specify options on the command line: these take precedence
|
||||
over any specified in the configuration file. For example:
|
||||
|
||||
% hadoop-ec2 launch-cluster --image-id ami-2359bf4a --instance-type c1.xlarge \
|
||||
my-hadoop-cluster 10
|
||||
|
||||
This command launches a 10-node cluster using the specified image and instance
|
||||
type, overriding the equivalent settings (if any) that are in the
|
||||
"my-hadoop-cluster" section of the configuration file. Note that words in
|
||||
options are separated by hyphens (--instance-type) while the corresponding
|
||||
configuration parameter is are separated by underscores (instance_type).
|
||||
|
||||
The scripts install Hadoop RPMs or Debian packages (depending on the OS) at
|
||||
instance boot time.
|
||||
|
||||
By default, Apache Hadoop 0.20.1 is installed. You can also run other versions
|
||||
of Apache Hadoop. For example the following uses version 0.18.3:
|
||||
|
||||
% hadoop-ec2 launch-cluster --env HADOOP_VERSION=0.18.3 \
|
||||
my-hadoop-cluster 10
|
||||
|
||||
CUSTOMIZATION
|
||||
=============
|
||||
|
||||
You can specify a list of packages to install on every instance at boot time
|
||||
using the --user-packages command-line option (or the user_packages
|
||||
configuration parameter). Packages should be space-separated. Note that package
|
||||
names should reflect the package manager being used to install them (yum or
|
||||
apt-get depending on the OS).
|
||||
|
||||
Here's an example that installs RPMs for R and git:
|
||||
|
||||
% hadoop-ec2 launch-cluster --user-packages 'R git-core' my-hadoop-cluster 10
|
||||
|
||||
You have full control over the script that is run when each instance boots. The
|
||||
default script, hadoop-ec2-init-remote.sh, may be used as a starting point to
|
||||
add extra configuration or customization of the instance. Make a copy of the
|
||||
script in your home directory, or somewhere similar, and set the
|
||||
--user-data-file command-line option (or the user_data_file configuration
|
||||
parameter) to point to the (modified) copy. hadoop-ec2 will replace "%ENV%"
|
||||
in your user data script with
|
||||
USER_PACKAGES, AUTO_SHUTDOWN, and EBS_MAPPINGS, as well as extra parameters
|
||||
supplied using the --env commandline flag.
|
||||
|
||||
Another way of customizing the instance, which may be more appropriate for
|
||||
larger changes, is to create you own image.
|
||||
|
||||
It's possible to use any image, as long as it i) runs (gzip compressed) user
|
||||
data on boot, and ii) has Java installed.
|
||||
|
||||
OTHER SERVICES
|
||||
==============
|
||||
|
||||
ZooKeeper
|
||||
=========
|
||||
|
||||
You can run ZooKeeper by setting the "service" parameter to "zookeeper". For
|
||||
example:
|
||||
|
||||
[my-zookeeper-cluster]
|
||||
service=zookeeper
|
||||
ami=ami-ed59bf84
|
||||
instance_type=m1.small
|
||||
key_name=tom
|
||||
availability_zone=us-east-1c
|
||||
public_key=PATH_TO_PUBLIC_KEY
|
||||
private_key=PATH_TO_PRIVATE_KEY
|
||||
|
||||
Then to launch a three-node ZooKeeper ensemble, run:
|
||||
|
||||
% ./hadoop-ec2 launch-cluster my-zookeeper-cluster 3 zk
|
||||
|
||||
PROVIDER-SPECIFIC DETAILS
|
||||
=========================
|
||||
|
||||
Rackspace
|
||||
=========
|
||||
|
||||
Running on Rackspace is very similar to running on EC2, with a few minor
|
||||
differences noted here.
|
||||
|
||||
Security Warning
|
||||
================
|
||||
|
||||
Currently, Hadoop clusters on Rackspace are insecure since they don't run behind
|
||||
a firewall.
|
||||
|
||||
Creating an image
|
||||
=================
|
||||
|
||||
Rackspace doesn't support shared images, so you will need to build your own base
|
||||
image to get started. See "Instructions for creating an image" at the end of
|
||||
this document for details.
|
||||
|
||||
Installation
|
||||
============
|
||||
|
||||
To run on rackspace you need to install libcloud by checking out the latest
|
||||
source from Apache:
|
||||
|
||||
git clone git://git.apache.org/libcloud.git
|
||||
cd libcloud; python setup.py install
|
||||
|
||||
Set up your Rackspace credentials by exporting the following environment
|
||||
variables:
|
||||
|
||||
* RACKSPACE_KEY - Your Rackspace user name
|
||||
* RACKSPACE_SECRET - Your Rackspace API key
|
||||
|
||||
Configuration
|
||||
=============
|
||||
|
||||
The cloud_provider parameter must be set to specify Rackspace as the provider.
|
||||
Here is a typical configuration:
|
||||
|
||||
[my-rackspace-cluster]
|
||||
cloud_provider=rackspace
|
||||
image_id=200152
|
||||
instance_type=4
|
||||
public_key=/path/to/public/key/file
|
||||
private_key=/path/to/private/key/file
|
||||
ssh_options=-i %(private_key)s -o StrictHostKeyChecking=no
|
||||
|
||||
It's a good idea to create a dedicated key using a command similar to:
|
||||
|
||||
ssh-keygen -f id_rsa_rackspace -P ''
|
||||
|
||||
Launching a cluster
|
||||
===================
|
||||
|
||||
Use the "hadoop-cloud" command instead of "hadoop-ec2".
|
||||
|
||||
After launching a cluster you need to manually add a hostname mapping for the
|
||||
master node to your client's /etc/hosts to get it to work. This is because DNS
|
||||
isn't set up for the cluster nodes so your client won't resolve their addresses.
|
||||
You can do this with
|
||||
|
||||
hadoop-cloud list my-rackspace-cluster | grep 'nn,snn,jt' \
|
||||
| awk '{print $4 " " $3 }' | sudo tee -a /etc/hosts
|
||||
|
||||
Instructions for creating an image
|
||||
==================================
|
||||
|
||||
First set your Rackspace credentials:
|
||||
|
||||
export RACKSPACE_KEY=<Your Rackspace user name>
|
||||
export RACKSPACE_SECRET=<Your Rackspace API key>
|
||||
|
||||
Now create an authentication token for the session, and retrieve the server
|
||||
management URL to perform operations against.
|
||||
|
||||
# Final SED is to remove trailing ^M
|
||||
AUTH_TOKEN=`curl -D - -H X-Auth-User:$RACKSPACE_KEY \
|
||||
-H X-Auth-Key:$RACKSPACE_SECRET https://auth.api.rackspacecloud.com/v1.0 \
|
||||
| grep 'X-Auth-Token:' | awk '{print $2}' | sed 's/.$//'`
|
||||
SERVER_MANAGEMENT_URL=`curl -D - -H X-Auth-User:$RACKSPACE_KEY \
|
||||
-H X-Auth-Key:$RACKSPACE_SECRET https://auth.api.rackspacecloud.com/v1.0 \
|
||||
| grep 'X-Server-Management-Url:' | awk '{print $2}' | sed 's/.$//'`
|
||||
|
||||
echo $AUTH_TOKEN
|
||||
echo $SERVER_MANAGEMENT_URL
|
||||
|
||||
You can get a list of images with the following
|
||||
|
||||
curl -H X-Auth-Token:$AUTH_TOKEN $SERVER_MANAGEMENT_URL/images
|
||||
|
||||
Here's the same query, but with pretty-printed XML output:
|
||||
|
||||
curl -H X-Auth-Token:$AUTH_TOKEN $SERVER_MANAGEMENT_URL/images.xml | xmllint --format -
|
||||
|
||||
There are similar queries for flavors and running instances:
|
||||
|
||||
curl -H X-Auth-Token:$AUTH_TOKEN $SERVER_MANAGEMENT_URL/flavors.xml | xmllint --format -
|
||||
curl -H X-Auth-Token:$AUTH_TOKEN $SERVER_MANAGEMENT_URL/servers.xml | xmllint --format -
|
||||
|
||||
The following command will create a new server. In this case it will create a
|
||||
2GB Ubuntu 8.10 instance, as determined by the imageId and flavorId attributes.
|
||||
The name of the instance is set to something meaningful too.
|
||||
|
||||
curl -v -X POST -H X-Auth-Token:$AUTH_TOKEN -H 'Content-type: text/xml' -d @- $SERVER_MANAGEMENT_URL/servers << EOF
|
||||
<server xmlns="http://docs.rackspacecloud.com/servers/api/v1.0" name="apache-hadoop-ubuntu-8.10-base" imageId="11" flavorId="4">
|
||||
<metadata/>
|
||||
</server>
|
||||
EOF
|
||||
|
||||
Make a note of the new server's ID, public IP address and admin password as you
|
||||
will need these later.
|
||||
|
||||
You can check the status of the server with
|
||||
|
||||
curl -H X-Auth-Token:$AUTH_TOKEN $SERVER_MANAGEMENT_URL/servers/$SERVER_ID.xml | xmllint --format -
|
||||
|
||||
When it has started (status "ACTIVE"), copy the setup script over:
|
||||
|
||||
scp tools/rackspace/remote-setup.sh root@$SERVER:remote-setup.sh
|
||||
|
||||
Log in to and run the setup script (you will need to manually accept the
|
||||
Sun Java license):
|
||||
|
||||
sh remote-setup.sh
|
||||
|
||||
Once the script has completed, log out and create an image of the running
|
||||
instance (giving it a memorable name):
|
||||
|
||||
curl -v -X POST -H X-Auth-Token:$AUTH_TOKEN -H 'Content-type: text/xml' -d @- $SERVER_MANAGEMENT_URL/images << EOF
|
||||
<image xmlns="http://docs.rackspacecloud.com/servers/api/v1.0" name="Apache Hadoop Ubuntu 8.10" serverId="$SERVER_ID" />
|
||||
EOF
|
||||
|
||||
Keep a note of the image ID as this is what you will use to launch fresh
|
||||
instances from.
|
||||
|
||||
You can check the status of the image with
|
||||
|
||||
curl -H X-Auth-Token:$AUTH_TOKEN $SERVER_MANAGEMENT_URL/images/$IMAGE_ID.xml | xmllint --format -
|
||||
|
||||
When it's "ACTIVE" is is ready for use. It's important to realize that you have
|
||||
to keep the server from which you generated the image running for as long as the
|
||||
image is in use.
|
||||
|
||||
However, if you want to clean up an old instance run:
|
||||
|
||||
curl -X DELETE -H X-Auth-Token:$AUTH_TOKEN $SERVER_MANAGEMENT_URL/servers/$SERVER_ID
|
||||
|
||||
Similarly, you can delete old images:
|
||||
|
||||
curl -X DELETE -H X-Auth-Token:$AUTH_TOKEN $SERVER_MANAGEMENT_URL/images/$IMAGE_ID

TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
|
||||
|
||||
1. Definitions.
|
||||
|
||||
"License" shall mean the terms and conditions for use, reproduction,
|
||||
and distribution as defined by Sections 1 through 9 of this document.
|
||||
|
||||
"Licensor" shall mean the copyright owner or entity authorized by
|
||||
the copyright owner that is granting the License.
|
||||
|
||||
"Legal Entity" shall mean the union of the acting entity and all
|
||||
other entities that control, are controlled by, or are under common
|
||||
control with that entity. For the purposes of this definition,
|
||||
"control" means (i) the power, direct or indirect, to cause the
|
||||
direction or management of such entity, whether by contract or
|
||||
otherwise, or (ii) ownership of fifty percent (50%) or more of the
|
||||
outstanding shares, or (iii) beneficial ownership of such entity.
|
||||
|
||||
"You" (or "Your") shall mean an individual or Legal Entity
|
||||
exercising permissions granted by this License.
|
||||
|
||||
"Source" form shall mean the preferred form for making modifications,
|
||||
including but not limited to software source code, documentation
|
||||
source, and configuration files.
|
||||
|
||||
"Object" form shall mean any form resulting from mechanical
|
||||
transformation or translation of a Source form, including but
|
||||
not limited to compiled object code, generated documentation,
|
||||
and conversions to other media types.
|
||||
|
||||
"Work" shall mean the work of authorship, whether in Source or
|
||||
Object form, made available under the License, as indicated by a
|
||||
copyright notice that is included in or attached to the work
|
||||
(an example is provided in the Appendix below).
|
||||
|
||||
"Derivative Works" shall mean any work, whether in Source or Object
|
||||
form, that is based on (or derived from) the Work and for which the
|
||||
editorial revisions, annotations, elaborations, or other modifications
|
||||
represent, as a whole, an original work of authorship. For the purposes
|
||||
of this License, Derivative Works shall not include works that remain
|
||||
separable from, or merely link (or bind by name) to the interfaces of,
|
||||
the Work and Derivative Works thereof.
|
||||
|
||||
"Contribution" shall mean any work of authorship, including
|
||||
the original version of the Work and any modifications or additions
|
||||
to that Work or Derivative Works thereof, that is intentionally
|
||||
submitted to Licensor for inclusion in the Work by the copyright owner
|
||||
or by an individual or Legal Entity authorized to submit on behalf of
|
||||
the copyright owner. For the purposes of this definition, "submitted"
|
||||
means any form of electronic, verbal, or written communication sent
|
||||
to the Licensor or its representatives, including but not limited to
|
||||
communication on electronic mailing lists, source code control systems,
|
||||
and issue tracking systems that are managed by, or on behalf of, the
|
||||
Licensor for the purpose of discussing and improving the Work, but
|
||||
excluding communication that is conspicuously marked or otherwise
|
||||
designated in writing by the copyright owner as "Not a Contribution."
|
||||
|
||||
"Contributor" shall mean Licensor and any individual or Legal Entity
|
||||
on behalf of whom a Contribution has been received by Licensor and
|
||||
subsequently incorporated within the Work.
|
||||
|
||||
2. Grant of Copyright License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,
|
||||
publicly display, publicly perform, sublicense, and distribute the
|
||||
Work and such Derivative Works in Source or Object form.
|
||||
|
||||
3. Grant of Patent License. Subject to the terms and conditions of
|
||||
this License, each Contributor hereby grants to You a perpetual,
|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
(except as stated in this section) patent license to make, have made,
|
||||
use, offer to sell, sell, import, and otherwise transfer the Work,
|
||||
where such license applies only to those patent claims licensable
|
||||
by such Contributor that are necessarily infringed by their
|
||||
Contribution(s) alone or by combination of their Contribution(s)
|
||||
with the Work to which such Contribution(s) was submitted. If You
|
||||
institute patent litigation against any entity (including a
|
||||
cross-claim or counterclaim in a lawsuit) alleging that the Work
|
||||
or a Contribution incorporated within the Work constitutes direct
|
||||
or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You
|
||||
meet the following conditions:
|
||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||
APPENDIX: How to apply the Apache License to your work.
|
||||
