---------------------------------------
Summary: Tool required to recover log and snapshot entries with
CRC errors
Key: ZOOKEEPER-2994
URL: https://issues.apache.org/jira/browse/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.
