Subject [jira] [Updated] (MAPREDUCE-1933) Improve automated testcase for tasktracker dealing with corrupted disk.
Date Wed, 19 Oct 2011 07:31:10 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1933?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Matt Foley updated MAPREDUCE-1933:
----------------------------------

         Description: 
Test "TestCorruptedDiskJob" was added in 0.20.203.0, to implement this test:
* After the TaskTracker has already run some tasks successfully, "corrupt" a disk by making
the corresponding mapred.local.dir unreadable/unwritable. Make sure that jobs continue to
succeed even though some tasks scheduled there fail. 

Cos provided suggestions for improvement in his comments of 23/Jul/10 18:40 and 30/Jul/10
01:51, but the patch was committed without these improvements nor response to them.  This
bug remains open until these improvements are implemented or responded to.
