hi,all
Our hadoop version is hadoop2.2, using fairscheduler.
Recently, our hadoop cluster encountered one problem, which is our jobs are all
stuck in prep states, no running jobs;
We checked the yarn log file and didnot find any error output and any blocked
job.
And then we used 'jstack' command to check resoucemanager process,found that 2
threads below were missing, which is:
IPC Parameter Sending Thread #0
IPC Parameter Sending Thread #1
We are confused about what happened and don't know how to solve the
problem. Just need your help! Looking forword for your reply!
Thanks a lot!
