Subject [jira] [Commented] (HBASE-10332) Missing .regioninfo file during daughter open processing
Date Mon, 13 Jan 2014 20:30:51 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13869935#comment-13869935
] 

Matteo Bertozzi commented on HBASE-10332:
-----------------------------------------

HRegion.createDaughterRegionFromSplits() uses HRegion.newHRegion() instead of createHRegion()
so the .regioninfo file is not created on daughter creation but on daughter open by the checkRegionInfoOnFileSystem..
This shouldn't be a problem, but let me see if I can change the code to use the create, or
at least write the .regioninfo on creation

regionserver.HRegionFileSystem: .regioninfo file not found for region: 490a58c14b14a59e8d303d310684f0b0
> {noformat}
> This is from HRegionFileSystem#checkRegionInfoOnFilesystem, which catches a FileNotFoundException
in this case and calls writeRegionInfoOnFilesystem to fix up the issue.
> Is this a bug in splitting?
