The default in 90 branch and trunk is 180000 (3 minutes) not 18000.

<name>zookeeper.session.timeout</name>
<value>180000</value>

We also figured that you MUST set the maxSessionTimeout to the same value
when using a stand alone ZooKeeper ensemble. The managed is fine, but the
stand alone without that extra option in the zoo.cfg will negotiate the
timeout to be a maximum of 20 x tickTime, so 40-60 seconds. In that case the
3 minutes value set in the hbase-default.xml is useless.
