Datanode should verify block sizes vs metadata on startup
---------------------------------------------------------
Key: HADOOP-4994
URL: https://issues.apache.org/jira/browse/HADOOP-4994
Project: Hadoop Core
Issue Type: Bug
Reporter: Brian Bockelman
I could have sworn this bug had been reported by someone else already, but I
can't find it on JIRA after searching.... apologies if this is a duplicate.
The datanode, upon starting up, should check and make sure that all block sizes
as reported via `stat` are the same as the block sizes as reported via the
block's metadata.
