# Hadoop-Aliyun module: Integration with Aliyun Web Services
<!-- MACRO{toc|fromDepth=0|toDepth=5} -->
## Overview
The `hadoop-aliyun` module provides support for Aliyun integration with
[Aliyun Object Storage Service (Aliyun OSS)](https://www.aliyun.com/product/oss).
The generated JAR file, `hadoop-aliyun.jar` also declares a transitive
dependency on all external artifacts which are needed for this support — enabling
downstream applications to easily use this support.
To make it part of Apache Hadoop's default classpath, simply make sure
that HADOOP_OPTIONAL_TOOLS in hadoop-env.sh has 'hadoop-aliyun' in the list.
### Features
* Read and write data stored in Aliyun OSS.
* Present a hierarchical file system view by implementing the standard Hadoop
[`FileSystem`](../api/org/apache/hadoop/fs/FileSystem.html) interface.
* Can act as a source of data in a MapReduce job, or a sink.
### Warning #1: Object Stores are not filesystems.
Aliyun OSS is an example of "an object store". In order to achieve scalability
and especially high availability, Aliyun OSS has relaxed some of the constraints
which classic "POSIX" filesystems promise.
Specifically
1. Atomic operations: `delete()` and `rename()` are implemented by recursive
file-by-file operations. They take time at least proportional to the number of files,
during which time partial updates may be visible. `delete()` and `rename()`
can not guarantee atomicity. If the operations are interrupted, the filesystem
is left in an intermediate state.
2. File owner and group are persisted, but the permissions model is not enforced.
Authorization occurs at the level of the entire Aliyun account via
[Aliyun Resource Access Management (Aliyun RAM)](https://www.aliyun.com/product/ram).
3. Directory last access time is not tracked.
4. The append operation is not supported.
### Warning #2: Directory last access time is not tracked,
features of Hadoop relying on this can have unexpected behaviour. E.g. the
AggregatedLogDeletionService of YARN will not remove the appropriate logfiles.
### Warning #3: Your Aliyun credentials are valuable
Your Aliyun credentials not only pay for services, they offer read and write
access to the data. Anyone with the account can not only read your datasets
—they can delete them.
Do not inadvertently share these credentials through means such as
1. Checking in to SCM any configuration files containing the secrets.
2. Logging them to a console, as they invariably end up being seen.
3. Defining filesystem URIs with the credentials in the URL, such as
`oss://accessKeyId:accessKeySecret@directory/file`. They will end up in
logs and error messages.
4. Including the secrets in bug reports.
If you do any of these: change your credentials immediately!
### Warning #4: The Aliyun OSS client provided by Aliyun E-MapReduce are different from this implementation
Specifically: on Aliyun E-MapReduce, `oss://` is also supported but with
a different implementation. If you are using Aliyun E-MapReduce,
follow these instructions —and be aware that all issues related to Aliyun
OSS integration in E-MapReduce can only be addressed by Aliyun themselves:
please raise your issues with them.

## Testing the hadoop-aliyun Module
To test `oss://` filesystem client, two files which pass in authentication
details to the test runner are needed.
1. `auth-keys.xml`
2. `core-site.xml`
Those two configuration files must be put into
`hadoop-tools/hadoop-aliyun/src/test/resources`.
### `core-site.xml`
This file pre-exists and sources the configurations created in `auth-keys.xml`.
For most cases, no modification is needed, unless a specific, non-default property
needs to be set during the testing.
### `auth-keys.xml`
This file triggers the testing of Aliyun OSS module. Without this file,
*none of the tests in this module will be executed*
It contains the access key Id/secret and proxy information that are needed to
connect to Aliyun OSS, and an OSS bucket URL should be also provided.
1. `test.fs.oss.name` : the URL of the bucket for Aliyun OSS tests
The contents of the bucket will be cleaned during the testing process, so
do not use the bucket for any purpose other than testing.
### Run Hadoop contract tests
Create file `contract-test-options.xml` under `/test/resources`. If a
specific file `fs.contract.test.fs.oss` test path is not defined, those
tests will be skipped. Credentials are also needed to run any of those
tests, they can be copied from `auth-keys.xml` or through direct
XInclude inclusion. Here is an example of `contract-test-options.xml`:
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<include xmlns="http://www.w3.org/2001/XInclude"
href="auth-keys.xml"/>
<property>
<name>fs.contract.test.fs.oss</name>
<value>oss://spark-tests</value>
</property>
<property>
<name>fs.oss.impl</name>
<value>org.apache.hadoop.fs.aliyun.AliyunOSSFileSystem</value>
</property>
<property>
<name>fs.oss.endpoint</name>
<value>oss-cn-hangzhou.aliyuncs.com</value>
</property>
<property>
<name>fs.oss.buffer.dir</name>
<value>/tmp/oss</value>
</property>
<property>
<name>fs.oss.multipart.download.size</name>
<value>102400</value>
</property>
</configuration>
