> Key: HBASE-27537
> URL: https://issues.apache.org/jira/browse/HBASE-27537
> Project: HBase
> Issue Type: Bug
> Components: regionserver
> Affects Versions: 2.4.15
> Reporter: mahuacai
> Assignee: mahuacai
> Priority: Critical
>
> Although table has a TTL set in the cluster，some regions do not perform
> periodic major compactions，and the expired TTL data is still stored in these
> large files. Not trigger the reason is that the periodic check of the thread
> according to number of files in the region If > hbase.hstore.compaction.min
> then major compaction is not triggered, Instead, minor compaction is
> triggered first. But minor compaction which excludes large files (by the
> hbase.hstore.compaction.max.size), when the larger files reach a certain
> number, the expired data under the larger files cannot be deleted normally.
