region_mover.rb fails to load -ROOT- region back to original server in deployment with no user tables. ------------------------------------------------------------------------------------------------------
Key: HBASE-5502 URL: https://issues.apache.org/jira/browse/HBASE-5502 Project: HBase Issue Type: Bug Components: scripts Affects Versions: 0.92.0 Environment: Ubuntu precise Reporter: James Page Priority: Minor The region_mover loadRegion function incorrectly uses 'isSuccessfulScan': {noformat} for r in regions exists = false begin exists = isSuccessfulScan(admin, r) rescue org.apache.hadoop.hbase.NotServingRegionException => e $LOG.info("Failed scan of " + e.message) end {noformat} isSuccessfulScan throws an exception when it fails rather than returning status. As a result empty regions don't get restored - this is the case in a fresh install (which is how I discovered this) with no user table. Modifying the code to set exists IF isSuccessfulScan does not throw an exception worked for me: {noformat} for r in regions exists = false begin isSuccessfulScan(admin, r) exists = true rescue org.apache.hadoop.hbase.NotServingRegionException => e $LOG.info("Failed scan of " + e.message) end {noformat} -- This message is automatically generated by JIRA.
