qian wang commented on HBASE-11625:
-----------------------------------

log is out of date and missing, the stack trace is almost 
blocktype.parse()->
blocktype.read->
new hfileblock()->
hfileblock.readBlockDataInternal()->
hfileblock.readBlockData()....

i am using 0.94 and occured this twice,i saw 0.98 that have the same code.

> 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
