Eric:
Thank you for your valuable reply??According to your tips, now my
collecor can collect data,and my hbase and chukwa also all normal??but when
i use the pig to run the ClusterSummary.pig . Always occur the following error
message??
org.apache.hadoop.hbase.ZooKeeperConnectionException: HBase is able to connect
to ZooKeeper but the connection closes immediately. This could be a sign that
the server has too many connections (30 is the default). Consider inspecting
your ZK server logs for that error and then make sure you are reusing
HBaseConfiguration as often as you can. See HTable's javadoc for more
information.

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
