Timothy Farkas commented on DRILL-6143: --------------------------------------- There seem to be cases where a drillbit does not send a response to the FragmentRunner with a larger timeout. There is likely another issue which can cause a response never to be sent in some cases. I will create a separate ticket for this case. > Make Fragment Runner's RPC Timeout a SystemOption > ------------------------------------------------- > > Key: DRILL-6143 > URL: https://issues.apache.org/jira/browse/DRILL-6143 > Project: Apache Drill > Issue Type: Bug > Affects Versions: 1.13.0 > Reporter: Timothy Farkas > Assignee: Timothy Farkas > Priority: Major > Fix For: 1.13.0 > > > Queries frequently fail sporadically on some clusters due to the following > error > {code} > oadd.org.apache.drill.common.exceptions.UserRemoteException: CONNECTION > ERROR: Exceeded timeout (25000) while waiting send intermediate work > fragments to remote nodes. Sent 5 and only heard response back from 4 nodes. > {code} > This error happens because the FragmentsRunner has a hardcoded timeout > RPC_WAIT_IN_MSECS_PER_FRAGMENT which is set at 5 seconds. Increasing the > timeout to 10 seconds resolved the sporadic failures that were observed. This > timeout should be changed to 10 and should also be configurable via the > SystemOptionManager -- This message was sent by Atlassian JIRA (v7.6.3#76005)
