Subject Two concurrent programs using the same hbase
Date Tue, 10 Sep 2013 19:01:24 GMT

I installed hbase on a gpfs directory and lanched it using

Two servers on this gpfs filesystem run a similar program.
This program accesses the hbase via GORA call:

this.dataStore = DataStoreFactory.getDataStore(Long.class,
                    Pageview.class, new Configuration());

However, when I am launching the second program on the second server, I get
the following exception:
     [java] Exception in thread "main" java.lang.RuntimeException:
org.apache.gora.util.GoraException: java.lang.RuntimeException:
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.

I do not know how to solve that. It is strange, since only *two* programs
use this HBASE connection.

Thanks a lot
