Please visit http://gerrit.cloudera.org:8080/2705 to look at the new patch set (#2). Change subject: kudu: add a flag for scanner timeout and increase default ...................................................................... kudu: add a flag for scanner timeout and increase default The default Kudu scanner RPC timeout is 15 seconds. This is a bit short for concurrent workloads: when I looped TPC-H queries on a small cluster for a few days, I saw one failure due to a timeout. When I dug into the logs, it seems that nothing went wrong -- just the disks were slow to respond at one point. This bumps the default to 60 seconds and makes it configurable in case we have any issues in production installs where we see timeouts even with the higher default.
