Hi, We have a Hive cluster (Hive 2.1.0+Tez 0.8.4) which works well for most queries. Though for some heavy ones we observe that sometimes are able to execute and sometimes get rejected. We are not sure why we get a rejection instead of getting them enqueued and wait for execution until resources in cluster are available again. We notice that the connection waits for a minute, and if fails to assign resources, will drop the query. Looking at configuration parameters, is not clear to us if this can be changed. Did anyone had a similar experience and can provide us some guidance?
Thank you in advance, Joze.
