Apache Hadoop Configurations for Sahara
=======================================

This directory contains default XML configuration files:

* core-default.xml
* hdfs-default.xml
* mapred-default.xml
* yarn-default.xml
* oozie-default.xml
* hive-default.xml

These files are applied for Sahara's plugin of Apache Hadoop version 2.7.1


Files were taken from here:

* `core-default.xml <https://github.com/apache/hadoop/blob/release-2.7.1/hadoop-common-project/hadoop-common/src/main/resources/core-default.xml>`_
* `hdfs-default.xml <https://github.com/apache/hadoop/blob/release-2.7.1/hadoop-hdfs-project/hadoop-hdfs/src/main/resources/hdfs-default.xml>`_
* `yarn-default.xml <https://github.com/apache/hadoop/blob/release-2.7.1/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/main/resources/yarn-default.xml>`_
* `mapred-default.xml <https://github.com/apache/hadoop/blob/release-2.7.1/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/resources/mapred-default.xml>`_
* `oozie-default.xml <https://github.com/apache/oozie/blob/release-4.2.0/core/src/main/resources/oozie-default.xml>`_
* `hive-default.xml <https://github.com/apache/hive/blob/release-0.11.0/conf/hive-default.xml.template>`_

XML configs are used to expose default Hadoop configurations to the users
through Sahara's REST API. It allows users to override some config values which
will be pushed to the provisioned VMs running Hadoop services as part of
appropriate xml config.
