Rohini Palaniswamy created TEZ-3008:
---------------------------------------
Summary: AM java.io.tmpdir should be set to $PWD/tmp
Key: TEZ-3008
URL: https://issues.apache.org/jira/browse/TEZ-3008
Project: Apache Tez
Issue Type: Improvement
Reporter: Rohini Palaniswamy
For tasks it is already done by TezRuntimeChildJVM
{code}
Path childTmpDir = new Path(Environment.PWD.$(),
YarnConfiguration.DEFAULT_CONTAINER_TEMP_DIR);
vargs.add("-Djava.io.tmpdir=" + childTmpDir);
{code}
Need to do this in AM as well. Mapreduce has uber mode which usually causes
more problem (MAPREDUCE-6576), when user code writes to java.io.tmpdir as it
defaults to /tmp in AM and fills up disk space on cluster nodes. Even though
there is no uber mode with Tez AM that can cause problem, there is still the
chance that the output committer code of users which run in AM can write
something to java.io.tmpdir.
