Mikalai Parafeniuk updated HAMA-524:
------------------------------------
Attachment: eof_exception.zip
Hi Suraj. I checked that I am running hdfs and hama from the same user one more
time. Now I am getting EOFException. Also I have found some suspicious lines in
log files.
Hadoop NameNode log:
{code}
2012-08-06 15:12:01,283 WARN org.apache.hadoop.ipc.Server: Incorrect header or
version mismatch from 127.0.0.1:46588 got version 4 expected version 3
{code}
Hama BspMaster log:
{code}
2012-08-06 15:12:01,297 ERROR org.apache.hama.bsp.BSPMaster: Can't get
connection to Hadoop Namenode!
java.io.IOException: Call to localhost/127.0.0.1:54310 failed on local
exception: java.io.EOFException
{code}
Maybe the problem is that I have installed incompatible versions of Hadoop and
Hama? I attached file with typescript of my terminal session and hadoop and
hama log files. Typescript can be viewed in readable version with help of cat
command. Configuration is the same, as in previous archive.
