[jira] Created: (MAPREDUCE-1085) For tasks, "ulimit -v -1" is being
run when user doesn't specify mapred.child.ulimit
For tasks, "ulimit -v -1" is being run when user doesn't specify mapred.child.ulimit
------------------------------------------------------------------------------------
Key: MAPREDUCE-1085
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1085
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: tasktracker
Affects Versions: 0.21.0, 0.22.0
Reporter: Ravi Gummadi
Fix For: 0.21.0
For tasks, "ulimit -v -1" is being run when user doesn't specify mapred.child.ulimit. Taking -1 as default value and using it in building the command is not right.

Ravi Gummadi commented on MAPREDUCE-1085:
-----------------------------------------
Tasks will pass. The issue is just the error message saying ulimit failed to set -1 as limit.

-----------------------------------------
We can check if the value is positive or not and add the ulimit command only if needed.

[jira] Updated: (MAPREDUCE-1085) For tasks, "ulimit -v -1" is being
run when user doesn't specify mapred.child.ulimit
Posted by "Vinod K V (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/MAPREDUCE-1085?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Vinod K V updated MAPREDUCE-1085:
---------------------------------
Priority: Blocker (was: Major)
This is a regression.
Before MAPREDUCE-478, if mapred.child.ulimit is not configured in mapred-site.xml, tasks run successfully.
After MAPREDUCE-478, they fail with error saying invalid options for ulimit (ulimit -v -1).
