[jira] [Updated] (MAPREDUCE-2850) TaskTracker disk failure handling
(MR-2413) has no test coverage
[ https://issues.apache.org/jira/browse/MAPREDUCE-2850?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ravi Gummadi updated MAPREDUCE-2850:
------------------------------------
Attachment: MR2850.v0.patch
Attaching first-cut patch that adds unit test for MR-2413.
The unit test checks if good mapred local dirs of TaskTracker are getting updated or not when disks fail. To mimic disk failure, I replaced the specific mapred-local-directory with a regular-file of the same name --- thus leading to DiskChecker.checkDir() to fail.
Please review the patch and provide your comments.
