[jira] [Created] (MAPREDUCE-2592) TT should fail task immediately
if userlog dir cannot be created
TT should fail task immediately if userlog dir cannot be created
----------------------------------------------------------------
Key: MAPREDUCE-2592
URL: https://issues.apache.org/jira/browse/MAPREDUCE-2592
Project: Hadoop Map/Reduce
Issue Type: Improvement
Components: tasktracker
Affects Versions: 0.23.0
Reporter: Todd Lipcon
Fix For: 0.23.0
Currently, TaskRunner will log the message "mkdirs failed. Ignoring" if it fails to mkdir the userlog directory for a task. Then, it goes on to spawn taskjvm.sh which tries to redirect output into the userlogs dir, thus failing with exit code 1. This leads to error messages that are very hard to diagnose ("task failed with exit status 1") in cases where the userlog directory has either become inaccessible or has reached the maximum number of dirents (32000 in ext3)

[jira] [Commented] (MAPREDUCE-2592) TT should fail task immediately

Esteban Gutierrez commented on MAPREDUCE-2592:
----------------------------------------------
The problem propagates very quickly to all the nodes after a single TaskTracker has reached that state and more jobs are submitted. This problem can bring down the whole cluster since all the TT will be blacklisted.
A sample stacktrace:

-------------------------------
Attachment: MAPREDUCE-2592.r1.diff
A WIP patch that makes the log creating method throw an IOE instead of simply logging a WARN.
No tests added yet. Would appreciate some help on writing one!
