Hi,
Do you see any errors in HMaster and Regionserver logs?
Alex.

Subject: issue with nutch-gora+hbase+zookeeper
Hi everyone
I am having this problem for couple of days now and would appreciate any
idea or suggestion that any one might have. I am using nutch 2.x with
hbase. due to nutch requirement I need to use older version of hbase (I
am using 0.90.6 over hadoop 1.1.1 with 10 nodes with zookeepr 3.5.0
[trunk] )
hbase seems to be running fine, thou I appreciate if someone can show me
how I can actually test it systematically. but I seem to be able to
create and read data from hbase, but when I run any nutch command
something very similar to this happens as soon as the job starts
running. this is for example, the output of nutch inject
13/02/22 12:07:30 INFO mapred.JobClient: map 0% reduce 0%
13/02/22 12:07:52 INFO mapred.JobClient: Task Id :

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.

increased the number of connection to 200 in zoo.cfg, and also here is
what is in the zookeeper log file around that time:
