["Matteo Bertozzi (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-7537?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Matteo Bertozzi updated HBASE-7537:
-----------------------------------

    Attachment: HBASE-7537-v0.patch

Simple patch to fix the current state, and add a test to verify that the .regioninfo is present on creation and is recreated on region opening if missing.

Also fix a bad parm naming for a openHRegionInfo(). was tableDir instead of rootDir.

> After HBASE-5683 we have no longer the .regioninfo written on disk during the table creation.
> so, if we fail before adding entries to .META. we end up with regions on disk that has no information, and hbck is not able to recover this situation.
> The .regioninfo is written in checkRegioninfoOnFilesystem() that was called by initialize(), during the table creation and region opening. With HBASE-5683 we skip the call to initialize(), in during the region creation, to avoid to initialize the memstore & co.
