/user/haduser/input

11/12/14 14:21:00 INFO ipc.Client: Retrying connect to server: loca         


        

Answer 1

I had similar issues - Actually Hadoop was binding to IPv6. Then I Added - "export HADOOP_OPTS=-Djava.net.preferIPv4Stack=true " to $HADOOP_HOME/conf/hadoop-env.sh

Hadoop was binding to IPv6 even when I had disabled IPv6 on my system. Once I added it to env, started working fine.

Hope this helps someone.
