I am executing same hive query on table at different times. some times query is starting immediately and some times its taking time to start. I started looking at the resource manager to have a look at the cluster availability. I would like to know if there is any way where i can find the time of job submission. I am able to pick time of acceptance and time of running from yarn cluster metrics. Also i am seeing few jobs in accepted state for some time before going to running state even though lot of resources are available on hadoop cluster. Can some one share your experience on this job wait times before job enters to running state.
