> Auto repair tool for MDT out of sync
> ------------------------------------
>
> Key: HUDI-5436
> URL: https://issues.apache.org/jira/browse/HUDI-5436
> Project: Apache Hudi
> Issue Type: Bug
> Components: metadata
> Reporter: sivabalan narayanan
> Priority: Critical
> Fix For: 0.14.0
>
>
> Can we write a spark-submit to repair any out of sync issues w/ MDT. for eg,
> if MDT validation failed for a given table, we don't have a good way to fix
> the MDT.
> So, we should develop a sparksubmit job which will try to deduce from which
> commit the out of sync happens and try to fix just the delta.
>
> idea here is:
> Try running validation job for latest files at every commit starting from
> latest in reverse chronological order. At some point validation will succeed.
> Lets call it commit N.
> we can add savepoint to MDT at commit N and restore the table to that commit
> N.
> and then we can take any new commits after commitN from data table and apply
> them one by one to MDT.
>
> Once complete, we can run validation tool again to ensure its in good shape.
