[jira] [Created] (MAPREDUCE-4250) hadoop-config.sh missing variable
exports, causes Yarn jobs to fail with ClassNotFoundException MRAppMaster
Patrick Hunt created MAPREDUCE-4250:
---------------------------------------
Summary: hadoop-config.sh missing variable exports, causes Yarn jobs to fail with ClassNotFoundException MRAppMaster
Key: MAPREDUCE-4250
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4250
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: nodemanager
Reporter: Patrick Hunt
Assignee: Patrick Hunt
This is the MR side of HADOOP-8393
If you start a pseudo distributed yarn using "start-yarn.sh" you need to specify exports for HADOOP_COMMON_HOME, HADOOP_HDFS_HOME, YARN_HOME, YARN_CONF_DIR, and HADOOP_MAPRED_HOME in hadoop-env.sh (or elsewhere), otherwise the spawned node manager will be missing
these in it's environment. This is due to start-yarn using yarn-daemons. With this fix it's possible to start yarn (etc...) with only HADOOP_CONF_DIR specified in the environment. Took some time to track down this failure, so seems worthwhile to fix.

------------------------------------
Attachment: MAPREDUCE-4250.patch
Exported the necessary vars. I tested by packaging everything up, starting start-dfs and start-yarn (with a single "localhost" slave) and then running a pi job from examples. Works with the patch, doesn't w/o.
