Hi,
Thank you the information. I moved to hama 0.7.0 and I still have the same
problem.
When I run % bin/hama bspmaster, I am getting the following exception
INFO http.HttpServer: Port returned by
webServer.getConnectors()[0].getLocalPort() before open() is -1. Opening
the listener on 40013

*Why zookeeper settings in hama-site.xml are (right now, I am using just
two servers 172.17.0.3 and 172.17.0.7)*
<property>
<name>hama.zookeeper.quorum</name>
<value>172.17.0.3,172.17.0.7</value>
<description>Comma separated list of servers in the
ZooKeeper quorum.
For example, "host1.mydomain.com,host2.mydomain.com,
host3.mydomain.com".
By default this is set to localhost for local and
pseudo-distributed modes
of operation. For a fully-distributed setup, this should
be set to a full
list of ZooKeeper quorum servers. If HAMA_MANAGES_ZK is
set in hama-env.sh
this is the list of servers which we will start/stop
ZooKeeper on.
</description>
</property>
......
<property>
<name>hama.zookeeper.property.clientPort</name>
<value>2181</value>
</property>
Is something wrong with my settings ?
