Greetings !<br><br>I created  a star cluster on EC2 and use qsub to submit jobs. It used to work well. From this afternoon, after I requested for additional EC2 instance from Amazon, the issue comes out.<br><br>Only the jobs submitted to the master node are executed. Other jobs disappeared just in no time.  Some diagonosis is as below. Any helps are appreciated !<br>
