Huaxiang Sun commented on HBASE-27366: -------------------------------------- Thanks [~zhangduo]. Will take a more close look based on your input, will try to come up with an unitest case to reproduce the issue. also correct the version to 2.4.5. > split or merge removed region under snapshot > -------------------------------------------- > > Key: HBASE-27366 > URL: https://issues.apache.org/jira/browse/HBASE-27366 > Project: HBase > Issue Type: Bug > Components: snapshots > Affects Versions: 2.4.5 > Reporter: Huaxiang Sun > Priority: Major > > We run into snapshot failures for one table with large number of regions. The > event sequence is like the following: > > # Snapshot process lists all regions for one table. > # Normalize kicks in to split some regions for the table under snapshot. > # split finishes and major compaction finishes. The parent region is moved > to archive. > # When the Snapshot processes the parent region, it does not exist and > snapshot fails. > Since snapshot process acquires the table lock, but there is no table lock > acquired in split or merge process, they crash into each other. -- This message was sent by Atlassian Jira (v8.20.10#820010)
