             Summary: Tool required to recover log and snapshot entries with 
CRC errors
                 Key: ZOOKEEPER-2994
             Project: ZooKeeper
          Issue Type: New Feature
            Reporter: Andor Molnar
            Assignee: Andor Molnar

In the even that the zookeeper transaction log or snapshot become corrupted and 
fail CRC checks (preventing startup) we should have a mechanism to get the 
cluster running again.

Previously with achieved this by loading the broken transaction log with a 
modified version of ZK with disabled CRC check and forced it to snapshot.

It'd very handy to have a tool which can do this for us. LogFormatter and 
SnapshotFormatter have already been designed to dump log and snapshot files, 
it'd be nice to extend their functionality and add ability for such recovery.
