[jira] [Commented] (MAPREDUCE-4872) MapReduce JVM launch does not
use correct working directory on Windows
[ https://issues.apache.org/jira/browse/MAPREDUCE-4872?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13531297#comment-13531297 ]
Xuan Gong commented on MAPREDUCE-4872:
--------------------------------------
Run the unix command:
sudo find . -name '*.java' -print0 | xargs -0 grep -l 'Environment.PWD'
Find these java files which contains Environment.PWD, and need to change to Environment.CD when it is WINDOWS Environment.

> {{MapReduceChildJVM#getVMCommand}} sets java.io.tmpdir by using environment variable PWD as the root of the path. On Windows, %PWD% likely will not be defined. Instead, we need to use %CD%. Any part of the codebase that uses {{Environment#PWD}} is likely to be impacted by this.
