Re: IO Exception on startup
Hi, Yes Hbase is working but our application which uses hbase still not able to connect to hbase and gives the following error on startup:
2010-01-03 02:56:41,809 INFO [main] hbase.client.HConnectionManager$TableServers (HConnectionManager.java:336) - getMaster attempt 7 of 10 failed; retrying after sleep of 16000
java.io.IOException: org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /hbase/master
at org.apache.hadoop.hbase.zookeeper.ZooKeeperWrapper.readAddressOrThrow(ZooKeeperWrapper.java:331)
at org.apache.hadoop.hbase.zookeeper.ZooKeeperWrapper.readMasterAddressOrThrow(ZooKeeperWrapper.java:240)
at org.apache.hadoop.hbase.client.HConnectionManager$TableServers.getMaster(HConnectionManager.java:318)
at org.apache.hadoop.hbase.client.HBaseAdmin.<init>(HBaseAdmin.java:72)
Do you suggest anything may cause this exception ?? what we should look for?
Thanks.

Re: IO Exception on startup
Posted by alaa nobani <al...@yahoo.com>.
Hi,
We dont have distributed system/operations,actually its all running on localhost, what I found strange is that we have the following in configuration:
<property>
<name>hbase.master</name>
<value>localhost:10015</value>
<description>The host and port that the HBase master runs at. </description>
</property>
but no service is listening on port 10015 ? why?

Re: IO Exception on startup
Posted by Jean-Daniel Cryans <jd...@apache.org>.
Per http://hadoop.apache.org/hbase/docs/r0.20.2/api/overview-summary.html#fully-distrib
hbase.master isn't specified there anymore. You must set
hbase.zookeeper.quorum which by default is "localhost".
