[jira] [Commented] (HBASE-7537) .regioninfo not created by
createHRegion()
[ https://issues.apache.org/jira/browse/HBASE-7537?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13552946#comment-13552946 ]
Matteo Bertozzi commented on HBASE-7537:
----------------------------------------
Maybe I can fill a follow up jira, to move out the the region on-disk creation code (region dir + .regioninfo) since we don't in the table creation case we don't want to initialize the region (call constructor and so on)
{code}
HRegion region = HRegion.createHRegion(newRegion,
fileSystemManager.getRootDir(), conf, hTableDescriptor, null,
false, true);
region.close();
{code}

> 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.
