---------------------------------------
Summary: DataServer.send() should throw a UserRpcException instead of returning
Ack.Fail
Key: DRILL-4252
URL: https://issues.apache.org/jira/browse/DRILL-4252
Project: Apache Drill
Issue Type: Improvement
Components: Execution - RPC
Affects Versions: 1.0.0
Reporter: Deneche A. Hakim
When a fragment sends data to another fragment and an error occurs in DataServer.send() on
the receiving side, the method logs the error and return an Ack.Fail to the sender without
any detail of the root cause. This causes the query to fail with a generic "Data not accepted
downstream" error.
DataServer.send() should throw a UserRpcException instead so the root cause can be propagated
back to the user.
