             Summary: Fix filegroup and commit time for an index type when indexing with FILES partition
                 Key: HUDI-4253
                 URL: https://issues.apache.org/jira/browse/HUDI-4253
             Project: Apache Hudi
          Issue Type: Bug
            Reporter: Sagar Sumit
             Fix For: 0.12.0


This is a followup of the discussion in HUDI-4156.

```

When both FILES and COLUMN_STATS are being initialized together, FILES partition takes the timestamp of latest completed commit in data table timeline, while COLUMN_STATS takes up new index commit time. and while enabling COLUMN_STATS partition, FSview does not return any file slices and so we end up setting file group count for COLUMN_STATS to 1.

```

We need to ensure that once the metadata partition is initialized, then the subsequent files in the partition pick the corresponding commit time from the timeline.
