    Hello,

    I installed HDP 1.3 cluster using Ambari. As I create hbase table in HIVE shell, log shows following error:

    2013-10-03 12:00:39,644 WARN zookeeper.ClientCnxn (ClientCnxn.java:run(1089)) – Session 0x0 for server null, unexpected error, closing socket connection and attempting reconnect

    I did specify the parent node as “hbase-unsecure” in hive-core.xml. what is the reason?

    1. the version of hbase/ZK in HIVE lib are not the same in cluster?
    2. Hive attempted to connect ZK on localhost? how can I specify ZK host?

    Thanks!

    Hi Lebing,

    Try add property hbase.zookeeper.quorum.

    Thanks,

    Hi,
    I have been trying to connect to hbase table through Java api.

    “WARN zookeeper.RecoverableZooKeeper: Possibly transient ZooKeeper exception: org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /hbase-unsecure/master”

    This is included in the hbase-site.xml

    <property>
    <name>zookeeper.znode.parent</name>
    <value>/hbase-unsecure</value>
    </property>

    Also, when I try ‘zookeeper-client’ I get connection refused error.

    Could someone advice on this?

    Thank you,
    Sunitha
