Raghu Angadi updated HADOOP-1955:
---------------------------------
Attachment: HADOOP-1955.patch
Updated patches have infinite time. Only to change is to change '60' to '-1'.
One issue with not having a timeout is that when the test framework times out,
we don't have access to the log, which makes it hard to debug.

> When replicating corrupted block, receiving side rejects the block due to

> Fsck shows those blocks as under-replicated.
