--------------------------------------------
Summary: MR jobs are failing with Could not find or load main
class for MRAppMaster
Key: MAPREDUCE-7055
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7055
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Rohith Sharma K S
It is observed that MR jobs are failing with *Error: Could not find or load
main class org.apache.hadoop.mapreduce.v2.app.MRAppMaster" even though
HADOOP_MAPRED_HOME is set in mapred-site.xml
Tried building tar.gz in branch-3.0 and seems works fine with same
configurations. But in branch-3.1 and trunk, it is failing. I got
launch_container.sh for both and compared classpath exported before launching
AM. Both classpath entries are same, but AM launching is failing with above
mentioned error.
Its better to confirm as 3.1 release is going to happen soon.
