Jason Lowe created MAPREDUCE-6472: ------------------------------------- Summary: MapReduce AM should have java.io.tmpdir=./tmp to be consistent with tasks Key: MAPREDUCE-6472 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6472 Project: Hadoop Map/Reduce Issue Type: Bug Components: mr-am Affects Versions: 2.6.0 Reporter: Jason Lowe
MapReduceChildJVM.getVMCommand ensures that all tasks have -Djava.io.tmpdir=./tmp set as part of the task command-line, but this is only used for tasks. The AM itself does not have a corresponding java.io.tmpdir setting. It should also use the same tmpdir setting to avoid cases where the AM JVM wants to place files in /tmp by default. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
