[Apache Whirr](http://whirr.apache.org/) is a set of libraries for launching cloud services. For Druid, Whirr serves as an easy way to launch a cluster in Amazon AWS by using simple commands and configuration files (called *recipes*).
**NOTE:** Whirr will install Druid 0.5.x. At this time Whirr can launch Druid 0.5.x only, but in the near future will support Druid 0.6.x. You can download and install your own copy of Druid 0.5.x [here](http://static.druid.io/artifacts/releases/druid-services-0.5.7-bin.tar.gz).
**NOTE:** Whirr will install Druid 0.6.121. Also, it doesn't work with JDK1.7.0_55. JDK1.7.0_45 recommended.
You'll need an AWS account, and an EC2 key pair from that account so that Whirr can connect to the cloud via the EC2 API. If you haven't generated a key pair, see the [AWS documentation](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-key-pairs.html) or see this [Whirr FAQ](http://whirr.apache.org/faq.html#how-do-i-find-my-cloud-credentials).
You'll need an AWS account, S3 Bucket and an EC2 key pair from that account so that Whirr can connect to the cloud via the EC2 API. If you haven't generated a key pair, see the [AWS documentation](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-key-pairs.html) or see this [Whirr FAQ](http://whirr.apache.org/faq.html#how-do-i-find-my-cloud-credentials).
### Installing Whirr
You must use a version of Whirr that includes and supports a Druid recipe. You can do it so in one of two ways:
#### Build the Following Version of Whirr
Clone the code from [https://github.com/rjurney/whirr/tree/trunk](https://github.com/rjurney/whirr/tree/trunk) and build Whirr:
Clone the code from [https://github.com/druid-io/whirr](https://github.com/druid-io/whirr) and build Whirr:

cd whirr
git checkout trunk

The Whirr recipe for Druid is the configuration file `$WHIRR_HOME/recipies/druid.properties`. You can edit this file to suit your needs -- it is annotated and self-explanatory. Here are some hints about that file:
* Set `whirr.location-id` to a specific AWS region (e.g., us-east-1) if desired, else one will be chosen for you.
* You can choose the hardware used with `whirr.hardware-id` to a specific instance type (e.g., m1.large). If you don't choose an image via `whirr.image-id` (image must be compatible with hardware), you'll get plain vanilla Linux.
* You can choose the hardware used with `whirr.hardware-id` to a specific instance type (e.g., m1.large). By default druid.properties, m3.2xlarge (broker, historical, middle manager), m1.xlarge (coordinator, overlord), and m1.small (zookeeper, mysql) are used.
* If you don't choose an image via `whirr.image-id` (image must be compatible with hardware), you'll get plain vanilla Linux. Default druid.properties uses ami-018c9568 (Ubuntu 12.04).
* SSH keys (not password protected) must exist for the local user. If they are in the default locations, `${sys:user.home}/.ssh/id_rsa` and `${sys:user.home}/.ssh/id_rsa.pub`, Whirr will find them. Otherwise, you'll have to specify them with `whirr.private-key-file` and `whirr.public-key-file`.
* Be sure to specify the absolute path of the Druid realtime spec file `realtime.spec` in `whirr.druid.realtime.spec.path`.
* Two Druid cluster templates (see `whirr.instance-templates`) are provided: a small cluster running on a single EC2 instance, and a larger cluster running on multiple instances. The first is a good test case to start with.
* Also make sure to specify the correct S3 bucket. Otherwise the cluster won't be able to process tasks.
* Two Druid cluster templates (see `whirr.instance-templates`) are provided: a small cluster running on a single EC2 instance, and a larger cluster running on multiple instances.

In order to configure each node, you can edit `services/druid/src/main/resources/functions/start_druid.sh` for JVM configuration and `services/druid/src/main/resources/functions/configure_[NODE_NAME].sh` for specific node configuration. For more information on configuration, read the Druid documentations about it (http://druid.io/docs/0.6.116/Configuration.html).

% $WHIRR_HOME/bin/whirr destroy-cluster --config $WHIRR_HOME/recipes/druid.properties
```
### Testing the Cluster
Now you can run an indexing task and a simple query to see if all the nodes have launched correctly. We are going to use a Wikipedia example again. For a realtime indexing task, run the following command:
```bash
curl -X 'POST' -H 'Content-Type:application/json' -d @#{YOUR_DRUID_DIRECTORY}/examples/indexing/wikipedia_realtime_task.json #{OVERLORD_PUBLIC_IP_ADDR}:#{PORT}/druid/indexer/v1/task
```
Issuing the request should return a task ID.
To check the state of the overlord, open up your browser and go to `#{OVERLORD_PUBLIC_IP_ADDR}:#{PORT}/console.html`.
Next, go to `#{COORDINATOR_PUBLIC_IP_ADDR}:#{PORT}`. Click "View Information about the Cluster"->"Full Cluster View." You should now see the information about servers and segments. If the cluster runs correctly, Segment dimensions and Segment binaryVersion fields should be filled up. Allow few minutes for the segments to be processed.
Now you should be able to query the data using broker's public IP address.

## What should I set my JVM heap?
The size of the JVM heap really depends on the type of Druid node you are running. Below are a few considerations.
[Broker nodes](Broker.html) can use the JVM heap as a query cache and thus, the size of the heap will affect on the number of results that can be cached. Broker nodes do not require off-heap memory and generally, heap sizes can be set to be close to the maximum memory on the machine (leaving some room for JVM overhead). The heap is used to merge results from different real-time and historical nodes, along with other computational processing.
[Broker nodes](Broker.html) uses the JVM heap mainly to merge results from historicals and real-times. Brokers also use off-heap memory and processing threads for groupBy queries.
[Historical nodes](Historical.html) use off-heap memory to store intermediate results, and by default, all segments are memory mapped before they can be queried. The more off-heap memory is available, the more segments can be served without the possibility of data being paged onto disk. On historicals, the JVM heap is used for [GroupBy queries](GroupByQuery.html), some data structures used for intermediate computation, and general processing.
[Historical nodes](Historical.html) use off-heap memory to store intermediate results, and by default, all segments are memory mapped before they can be queried. Typically, the more memory is available on a historical node, the more segments can be served without the possibility of data being paged on to disk. On historicals, the JVM heap is used for [GroupBy queries](GroupByQuery.html), some data structures used for intermediate computation, and general processing. One way to calculate how much space there is for segments is: memory_for_segments = total_memory - heap - direct_memory - jvm_overhead.
[Coordinator nodes](Coordinator nodes) do not require off-heap memory and the heap is used for loading information about all segments to determine what segments need to be loaded, dropped, moved, or replicated.
