Subject Problem connecting to HBase using Java Client
Date Thu, 02 Dec 2010 20:19:41 GMT
Hidey Ho,
  I have a three node cluster up running
Hadoop 20.20.2+737.tar  (from Cloudera)
HBase  0.89.20100924+28 (from Cloudera)

When I do a JPS everything looks ok.

I am trying to connect to HBase using a Java Client.

    final Configuration config = HBaseConfiguration.create();
    m_trafficTable = new HTable(config, TRAFFIC_LOG_TABLE_NAME);
    m_trafficTable.setAutoFlush(false);  // performance
    m_trafficTable.setWriteBufferSize(12582912L);  // performance

When the client tries to create the configuration I get the following...

2010-12-02 11:35:59,971 INFO  [Import Click Log Thread] zookeeper.ZooKeeperWrapper(195): Reconnecting

This just repeats.

Any ideas?
