Description

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.
