> 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 connection,
connectString=localhost:61181 sessionTimeout=120000 watcher=master:484800x0, quorum=localhost:61181,
baseZNode=/ams-hbase-unsecure
