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.
