Hello Mahmood Naderan,
When client is trying to connect to server with configured port(and address)
and server is not started with that port then client will retry ( and you will
get following error..)..
I can able to trace that Namenode is not running From JPS report which you had
posted..Please check the namenode logs ( location :
/home/mahmood/bigdatabench/apache/hadoop-1.0.2/libexec/../logs/hadoop-mahmood-namenode-tiger.out/log)

Subject: ipc.Client: Retrying connect to server
Hello,I have done all steps (as far as I know) to bring up the hadoop. However,
I get the this error
15/04/17 12:45:31 INFO ipc.Client: Retrying connect to server:
localhost/127.0.0.1:54310. Already tried 0 time(s).
There are a lot of threads and posts regarding this error and I tried them.
However still stuck at this error :(
Can someone help me? What did I wrong?
