<h2>Orphan Regions on RegionServer</h2>
</div>
</div>
+ <p>
+ <span>
+ The below are Regions we've lost account of. To be safe, run bulk
load of any data found in these Region orphan directories back into the HBase
cluster.
+ First make sure hbase:meta is in healthy state; run 'hbkc2 fixMeta'
to be sure. Once this is done, per Region below, run a bulk
+ load -- '$ hbase completebulkload REGION_DIR_PATH TABLE_NAME' -- and
then delete the desiccated directory content (HFiles are removed upon
successful load; all that is left are empty directories
Review comment:
Yuck. In a table with lots of busted regions, this `completeBulkLoad` would
be tedious. Maybe we need a new `hbck2 bulkloadOrphanedRegions` command that
can identify the orphans, bulk load them, and clean up the husks.
