Hi,

for some reason the hbase master does not come up anymore.

I get the following msg error:

8:55:53.701 AM FATAL org.apache.hadoop.hbase.master.HMaster

Master server abort: loaded coprocessors are: []

  8:55:53.701 AM FATAL org.apache.hadoop.hbase.master.HMaster

Unhandled exception. Starting shutdown.
org.apache.hadoop.hbase.TableExistsException: hbase:namespace
  at org.apache.hadoop.hbase.master.handler.CreateTableHandler.prepare(CreateTableHandler.java:120)
  at org.apache.hadoop.hbase.master.TableNamespaceManager.createNamespaceTable(TableNamespaceManager.java:230)
  at org.apache.hadoop.hbase.master.TableNamespaceManager.start(TableNamespaceManager.java:85)
  at org.apache.hadoop.hbase.master.HMaster.initNamespace(HMaster.java:1059)
  at org.apache.hadoop.hbase.master.HMaster.finishInitialization(HMaster.java:920)
  at org.apache.hadoop.hbase.master.HMaster.run(HMaster.java:606)
  at java.lang.Thread.run(Thread.java:744)



Any idea?
FYI - I am running a secured cluster with CDH5.0

Thanks
