Bryan Beaudreault updated HDFS-17179:
-------------------------------------
Description:
We've been running into some data corruption issues recently. When a
ChecksumException is thrown, DFSInputStream correctly reports the block to the
NameNode which triggers deletion and re-replication of the replica. It's also
possible that we fail to even read the meta header for constructing the
checksum. This gets thrown as CorruptMetaHeaderException which is not handled
by DFSInputStream. We should handle this similarly to ChecksumException. See
stacktrace:
