Getting Connectivity error while executing mapReduce program



I am getting server error while running a mapReduce program.
i am getting error like “20/01/19 16:38:21 INFO ipc.Client: Retrying connect to server: cxln2.c.thelab-240901.internal/ Already tried 1 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=50, sleepTime=1000 MILLISECONDS)”

Can you please help with a solution?, i am mid of something to complete one execution ASAP.




There is some problem in YARN. I’m checking the logs.

In the mean while I have again restarted it.
