[jira] [Updated] (HBASE-7339) Splitting a hfilelink causes region
servers to go down.
[ https://issues.apache.org/jira/browse/HBASE-7339?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jonathan Hsieh updated HBASE-7339:
----------------------------------
Description:
Steps:
- Have a single region table with 15 hfiles in it.
- Snapshot it. (was done using online snapshot from HBASE-7321)
- Clone a snapshot
- region post-open task attempts to compact region. policy does not compact all files. (default seems to be 10)
- after compaction we have hfile links and real hfiles mixed in the region
- it starts splitting
- creating split references, opening daughers fails
- hfile links are "split", creating hfile link daughter refs. {{<<hfile>\-<region>\-<table>>.<parentregion>}}
- these "split" hfile links are interpreted as hfile links with table {{<table>.<parentregion>}} -> {{<<hfile>\-<region>>\-<<table>.<parentregion>>}} (groupings interpreted incorrectly)
- Since this is after the splitting PONR, this aborts the server. It then spreads to the next server.
