I am using CDH-5.7.6. Daemon is crashing quite often these days. Couple of incidents are almost similar. In both cases, there were 4-5 crashes with in span of 15 mins. Also, this has occured in all impalad's in the cluster and memory usage (mem_rss) were almost full in almost all daemons. Attaching crash report for debugging purpose. I am trying to understand the queries ran around that time. Thoughts?
