I am running a Hadoop cluster of about 40 machines, and I got some problem with the HDFS. When I try to connect to the HDFS, say using the 'hadoop fs -ls /' command, sometimes it needs to retry connect to HDFS: 12/04/25 11:22:01 INFO ipc.Client: Retrying connect to server: master/10.10.10.51:8020. Already tried 0 time(s).
And then it can connect to HDFS and return the result. But the process costs time and I am looking for some way to solve it. Is there something wrong with my Hadoop configurations? Or something wrong with the networking?
