Hello:
I am interesting in Hama project. I want to do some experimental work
with it. But I met a problem when I set up the Hama enviroment.
I have set up one Hadoop and a zooKeeper.
I have already one zooKeeper instance, so I disable zookeeper manager
in hama as followers in hama-env.sh:
export HAMA_MANAGES_ZK=false
And configure the settings in hama-site.xml
35 <property>
36 <name>hama.zookeeper.quorum</name>
37 <value>127.0.1.1</value>
38 </property>
39
40 <property>
41 <name>hama.zookeeper.property.clientPort</name>
42 <value>2181</value>
43 </property>
In my zoo.cfg in zookeeper-3.3.3, I also configure it as follows:
clientPort=2181
Then I start hama and run hama-0.20.0-examples.jar for PI test. It
generates errors:
2011-05-30 10:47:28,639 INFO org.apache.zookeeper.ClientCnxn: Opening
socket connection to server 127.0.1.1/127.0.1.1:21810
2011-05-30 10:47:28,640 WARN org.apache.zookeeper.ClientCnxn: Session
0x0 for server null, unexpected error, closing socket connection and
attempting reconnect

at
sun.nio.ch.SocketChannelImpl.finishConnect(SocketChannelImpl.java:574)
at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1078)
But if I change clientPort from 2181 to 21810 in my zoo.cfg in my
zookeeper-3.3.3, it works.
It seems that I couldn't change zookeeper clientPort. It is allowed
to be 21810. I can't change it to other value.
I don't know whether it is a bug for Hama.
Is there any people know it ?
Thank you!
B.R.
