Hi Roman!
Did you setup the default filesystem in hama-site.xml?
Please submit your hama-site.xml configuration.
Martin
hama-site.xml - pseudo-distributed mode
<configuration>
<property>
<name>bsp.master.address</name>
<value>localhost:40000</value>
<description>The address of the bsp master server. Either the
literal string "local" or a host:port for distributed mode
</description>
</property>
<property>
<name>fs.default.name</name>
<value>hdfs://localhost/</value>
<description>
The name of the default file system. Either the literal string
"local" or a host:port for HDFS.
</description>
</property>
<property>
<name>hama.zookeeper.quorum</name>
<value>localhost</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>
</configuration>
