sivabalan narayanan updated HUDI-4072:
--------------------------------------
Status: Open (was: In Progress)
> Clustering fails when there is an empty SCHEMA entry in commit metadata with
> deltastreamer
> ------------------------------------------------------------------------------------------
>
> Key: HUDI-4072
> URL: https://issues.apache.org/jira/browse/HUDI-4072
> Project: Apache Hudi
> Issue Type: Bug
> Components: deltastreamer
> Reporter: sivabalan narayanan
> Assignee: sivabalan narayanan
> Priority: Critical
> Labels: pull-request-available
> Fix For: 0.12.0
>
>
> when deltastreamer has an empty commit(no records to commit, but commit has
> to happen since checkpoint has changed), we add NULL_SCHEMA or empty string
> as schema in extra metadata for commits. This is having issues in follow up
> commits when write client is instantiated from this commit.
