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?
