This ensures that source and > destination of rename operation are on the same namespace volume. > Patch for 0.94 and trunk is attached for review. The patch modifies the > location of the backup directory from '/hbase-xxxxxxx' to > '/hbase/.hbcktmp-xxxxxxx' -- This message is automatically generated by JIRA.
