Apache Hadoop Configurations for Sahara
This directory contains default XML configuration files:
- core-default.xml,
- hdfs-default.xml,
- mapred-default.xml,
- yarn-default.xml
These files are applied for Sahara's plugin of Apache Hadoop version 2.3.0
Files were taken from here: https://github.com/apache/hadoop-common/blob/release-2.3.0/hadoop-common-project/hadoop-common/src/main/resources/core-default.xml https://github.com/apache/hadoop-common/blob/release-2.3.0/hadoop-hdfs-project/hadoop-hdfs/src/main/resources/hdfs-default.xml https://github.com/apache/hadoop-common/blob/release-2.3.0/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-common/src/main/resources/yarn-default.xml https://github.com/apache/hadoop-common/blob/release-2.3.0/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/resources/mapred-default.xml
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.
