Add option to fsck that checks the crc
--------------------------------------
Key: HADOOP-503
URL: http://issues.apache.org/jira/browse/HADOOP-503
Project: Hadoop
Issue Type: Improvement
Components: dfs
Affects Versions: 0.5.0
Reporter: Johan Oskarson
If I'm not mistaken the fsck command doesn't actually check the crc of the
blocks.
I just had a problem where a few blocks managed to get the size 0, fsck didn't
report this but
my hadoop programs started failing because some of the input data was corrupted.
An option in the fsck program to actually check the crc would be nice, even
though it would take a while to run.
