Review request for Ambari, Alejandro Fernandez, Aravindan Vijayan, and Sumit
Mohanty.
Bugs: AMBARI-14572
https://issues.apache.org/jira/browse/AMBARI-14572
Repository: ambari
Description
-------
Found out that we are not setting property "hbase.zookeeper.property.tickTime"
for embedded mode.
The AMS system initialization was stuck on Zookeeper being unresponsive for a
few minutes right at the start of the cluster.
The possible cause is still unknown, only explanation is a long gc pause .
However, Zookeeper session timedout on start. with the following message:
{code}
2016-01-05 10:24:10,000 INFO [SessionTracker] server.ZooKeeperServer: Expiring
session 0x152114fb0060001, timeout of 40000ms exceeded
{code}
We set the session timeout to 120 seconds however the server session expires in
20 * _default_tick_time_ (2 seconds)
We can definitely increase this 3 fold by setting a property which should
alleviate this situation.
*Note*: After auto-start brings up the daemon a second time, this does not
reoccur.
{code}
2016-01-05 10:23:24,906 INFO [main] zookeeper.ZooKeeper: Initiating client
