Subject Drill Queries Timing Out
Date Wed, 31 Aug 2016 15:28:35 GMT
I'm having some performance issues testing Drill on a large MapR cluster.
I've been building a cluster of 100 nodes for the past few weeks. When the
cluster had only 40 nodes, I ran a benchmark test where Drill performed
very well, returning in 80 seconds from counting a large table. After
adding the additional 60 nodes, the same benchmark test is not finishing.
It times out after approx. 5 minutes due to configured timeout value of
300000. My understanding of Drill is that performance should improve when
you increase the cluster size. Each drillbit is configured with 16G. Can
someone tell me if there are some configuration settings that can improve
this? Or, is there some point where Drill performance decreases when the
size of the cluster is too large?
