Appy commented on HBASE-11625:
------------------------------
[~ndimiduk] Committing this now.
The unittest for this was something that struck me after long hard thinking and
was the best thing i could do to test this. Testing this in live is not
possible because that'd require corrupting hfiles (or simulating it) in hdfs,
and i don't know how to do it.
Since this is core logic, any IT test should be enough to make sure that this
fix (which is significantly different than master branch's fix) doesn't break
anything.

> when using hbase checksum,call readBlockDataInternal() in hfileblock.java, it
> could happen file corruption but it only can switch to hdfs checksum
> inputstream till validateBlockChecksum(). If the datablock's header corrupted
> when b = new HFileBlock(),it throws the exception "Invalid HFile block magic"
> and the rpc call fail
