<name>zookeeper.session.timeout</name>
<value>10000</value>
<description>ZooKeeper session timeout. This option is not used by HBase
directly, it is for the internals of ZooKeeper. HBase merely passes it in
whenever a connection is established to ZooKeeper. It is used by ZooKeeper
for hearbeats. In milliseconds.
</description>
</property>
<property>
<name>zookeeper.retries</name>
<value>5</value>
<description>How many times to retry connections to ZooKeeper. Used for
reading/writing root region location, checking/writing out of safe mode.
Used together with ${zookeeper.pause} in an exponential backoff fashion
when making queries to ZooKeeper.

<name>zookeeper.pause</name>

<description>Sleep time between retries to ZooKeeper. In milliseconds. Used
together with ${zookeeper.retries} in an exponential backoff fashion when
making queries to ZooKeeper.

<name>zookeeper.znode.parent</name>
<value>/hbase</value>
<description>Root ZNode for HBase in ZooKeeper. All of HBase's ZooKeeper
files that are configured with a relative path will go under this node.
By default, all of HBase's ZooKeeper file patsh are configured with a
relative path, so they will all go under this directory unless changed.

<property>
<name>zookeeper.znode.rootserver</name>
<value>root-region-server</value>
<description>Path to ZNode holding root region location. This is written by
the master and read by clients and region servers. If a relative path is
given, the parent folder will be ${zookeeper.znode.parent}. By default,
this means the root location is stored at /hbase/root-region-server.

</property>
<property>
<name>zookeeper.znode.safemode</name>
<value>safe-mode</value>
<description>Path to ephemeral ZNode signifying cluster is out of safe mode.
This is created by the master when scanning is done. Clients wait for this
node before querying the cluster. If a relative path is given, the parent
folder will be ${zookeeper.znode.parent}. By default, this means the safe
mode flag is stored at /hbase/safe-mode.
