-------------------------------------
Summary: Queries Fail Due To Aggressive RPC Timeout
Key: DRILL-6143
URL: https://issues.apache.org/jira/browse/DRILL-6143
Project: Apache Drill
Issue Type: Bug
Reporter: Timothy Farkas
Assignee: Timothy Farkas
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
