-------------------------------
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.
