Another thing I am using hadoop in psuedo single node server. But even if I don't start Hbase I will have same error.
ERROR: 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. -- View this message in context: http://lucene.472066.n3.nabble.com/Hbase-with-Hadoop-tp3413950p3418992.html Sent from the Hadoop lucene-users mailing list archive at Nabble.com.
