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.
