Adar Dembo updated KUDU-2615:
-----------------------------
Fix Version/s: (was: 1.9.0)
> Add more tools for dealing with the WAL
> ---------------------------------------
>
> Key: KUDU-2615
> URL: https://issues.apache.org/jira/browse/KUDU-2615
> Project: Kudu
> Issue Type: Improvement
> Components: log
> Affects Versions: 1.8.0
> Reporter: Will Berkeley
> Assignee: Will Berkeley
> Priority: Major
>
> There's only one tool for dealing with WALs, the dump tool, which lets you
> see what's in the WAL by reading it like a Kudu server would and then dumping
> it as debug strings.
> We could probably use a few more, though. This JIRA serves as a tracking JIRA
> for new WAL tools and as a parent JIRA for some existing WAL tool JIRAs.
> Tools we could add or enhancements we could make:
> * 'kudu wal dump --debug' with batch offsets. This would have been useful to
> me a couple times when I've done WAL surgery.
> * 'kudu wal dump repair' maybe with truncate capability (KUDU-1503) or the
> capability to 'punch out' an entry.
> * A 'kudu wal compare' tool that can compare two WALs and show their
> differences, so the WALs of two replicas of the same tablet could be compared.
> * A 'kudu wal edit' tool that can edit some kinds of wal entries-- the use
> case for this is editing the hostports of peers in config change operations
> (KUDU-2396).
