Hi folks,
I recently upgraded to hbase 0.90.2 that runs with hadoop 0.20.1. And
I got the following errors in the hbase logs:
2011-04-09 02:28:02,429 INFO org.apache.zookeeper.ClientCnxn: Opening
socket connection to server localhost/127.0.0.1:2181
2011-04-09 02:28:02,430 WARN org.apache.zookeeper.ClientCnxn: Session
0x12f...... for server null, unexpected error, closing socket
connection and attempting reconnect
java.net.ConnectException: Connection refused

at
sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:567)
at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1119)
Hadoop is running ok. I did not have this problem with hbase 0.2x
before. I guess I must have missed something here.
I am running this in pseudo mode. With mostly default conf. Only
changes is to set Java_home and hadoop dfs address. The OS is untuntu
10.10.
What might have caused this problem? Thanks a lot.
William
