Connector error
Hi, Eric:
When I running the chukwa in cluster,I encountered a question about
the hbase Connector .My HBase normal run, But Connector error has
occurred, my hbase is 0.90.4 ,and hadoop is hadoop-1.0.0.chukwa is
chukwa-0.5.0 .
Connector.log error tips is :
2012-08-11 21:50:51,693 INFO Timer-2 HBaseWriter -
stat=HBaseWriter|dataRate=0
2012-08-11 21:50:51,766 INFO btpool0-1-SendThread(localhost:21818)
ClientCnxn - Opening socket connection to server localhost/127.0.0.1:21818
2012-08-11 21:50:51,767 WARN btpool0-1-SendThread(localhost:21818)
ClientCnxn - Session 0x0 for server null, unexpected error, closing socket
connection and attempting reconnect
java.net.ConnectException: Connection refused

at
sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:574)
at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1119)
As someone's advice ,i removed the IPV6 in /etc/hosts （：：1 localhost）and
disable the ipv6 functions.But still could not solve the problem。Can you
tell me how
to solve the problem? thanks！
Best regards ，

Hi Mason,
Are you using HBase provided ZooKeeper or standalone ZooKeeper? HBase
client in collector is trying to access ZooKeeper at port 21818, and
unable to connect because there is no ZooKeeper running on port 21818.
Standalone ZooKeeper is running at port 2181, and hbase-site.xml may
not have been configured correctly on the class path of collector.
HBASE_CONF_DIR should be defined in chukwa-env.sh for this to work
properly. Hope this helps.
regards,
Eric

You want the hadoop/chukwa list, not mahout.
