Subject [jira] [Updated] (HBASE-9698) HBCK does not handle tables with no regions left
Date Wed, 02 Oct 2013 01:51:23 GMT

     [ https://issues.apache.org/jira/browse/HBASE-9698?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Enis Soztutar updated HBASE-9698:

    Attachment: hbase-9698_v1.patch

Attaching a patch which solves the problem by ensuring that even though no region info is
loaded from meta or hdfs, we still keep track of the table, and if there are no regions for
a table, we treat this as a hole covering the entire range.

> hbck does not handle the case where all the regions of a table is gone. To reproduce
> 1. create table with one region 
> 2. delete the region directory
> 3. run hbck --repair, which removes the region from meta as well 
> 4. now, the meta won't contain the region, but the table dir in hdfs will be there.
