             Summary: Give more time for HBase system tables to be assigned
                 Key: AMBARI-16278
                 URL: https://issues.apache.org/jira/browse/AMBARI-16278
             Project: Ambari
          Issue Type: Improvement
            Reporter: Ted Yu


We have observed extended cluster downtime due to HBase system tables not being assigned at cluster start up.

The default values for the following two parameters are too low:

hbase.regionserver.executor.openregion.threads (default: 3)
hbase.master.namespace.init.timeout (default: 300000)

We set hbase.regionserver.executor.openregion.threads=200 and hbase.master.namespace.init.timeout=2400000 in some case to work around HBASE-14190.

Ambari can use 20 for hbase.regionserver.executor.openregion.threads and 2400000 for hbase.master.namespace.init.timeout as default value.
