Vasu Mariyala created YARN-1361:
-----------------------------------
Summary: Not able to run the map reduce jobs on multiple mini map
reduce clusters
Key: YARN-1361
URL: https://issues.apache.org/jira/browse/YARN-1361
Project: Hadoop YARN
Issue Type: Task
Components: resourcemanager
Reporter: Vasu Mariyala
Priority: Critical
As part of testing backup validation on the primary and dr clusters, we do the
following
a) Start two mini clusters with each mini cluster containing hdfs, map reduce
and hbase mini clusters.
b) Run the backup map reduce job on both the primary and secondary test mini
clusters
c) These jobs interfere with each other and the second job fails due to the
following
The application id is created by using the time stamp (static variable) and a
job counter (instance specific always starts with zero). Since a unit test is
ran on a single jvm, these jobs get the same application id and the second job
fails with tokens already exist error.
