sstable2json / sstablekeys should verify key order in -Data and -Index files
----------------------------------------------------------------------------
Key: CASSANDRA-1884
URL: https://issues.apache.org/jira/browse/CASSANDRA-1884
Project: Cassandra
Issue Type: Improvement
Components: Tools
Affects Versions: 0.7.0
Reporter: Karl Mueller
Priority: Minor
Some cassandra users use sstable2json and sstablekeys to check -Data and -Index
files for integrity. For example, if compaction fails, you can find out which
files are causing the compaction to fail because they're corrupt. One type of
corruption that can happen in both -Data and -Index files are keys getting out
of order. (This shouldn't happen, but it can) Cassandra catches this error
during compaction, but both tools didn't catch it.
This small patch simply causes an IO Exception during export if it finds out of
order keys.
Some further work on it may make this optional with a command-line switch - it
may be useful to export the data to json even though it's out of order to
manually play it back, or have another script re-order it.
