I have created 'usertable' and then tried to modify it couple times (added COMPRESSION), HBase (0.94.6) stopped working (Master could not finish initialization) I stopped the cluster and physically removed /hbase/usertable directory as well as all ZK local stores. Restarted. No success. I manually ran OfflineMetaRepair. Restarted. No success. This is FATAL error in Master's log file. For some reason, OfflineMetaRepair did not fix missing 'usertable'.
