Subject: Master aborts on start up - URGENT

This may be related to :

https://issues.apache.org/jira/browse/HBASE-8912


It has started when I tried to install and run YCSB. 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'.

Please, advise. This is a development cluster with a large volume of data.
