Project: Hadoop
Type: Bug
Components: mapred

Reporter: Hairong Kuang
Assigned to: Hairong Kuang
Fix For: 0.3
Currently if a task tracker is not able to write to any of its local directories, it continues to run and all the tasks assigned to it fail.
A task tracker should not start upif it has a problem reading/writing any of its local directories. It should abort if it gets the problem at run time.

[jira] Updated: (HADOOP-265) Abort tasktracker if it can not write
to its local directories
Posted by "Hairong Kuang (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/HADOOP-265?page=all ]
Hairong Kuang updated HADOOP-265:
---------------------------------
Attachment: mapred_disk.patch
In this patch, if a task tracker finds out that any of its local directories becomes not readable or writable, it logs the error. If all of its local directories are not readable/writable, it reports the problem to its job tracker and then aborts. When the job tracker receives the error report, it logs the error.
A task tracker detects disk problem at startup time and before it starts a new task. A task tracker will not start if all its local directories are not readable or writable.
