-----------------------------------
Summary: Race condition during shutdown of RemoteDriver, error
messages aren't always sent
Key: HIVE-18766
URL: https://issues.apache.org/jira/browse/HIVE-18766
Project: Hive
Issue Type: Sub-task
Components: Spark
Reporter: Sahil Takiar
When we send an error during shutdown of the {{RemoteDriver}}, we don't wait
for the error message to be sent. We just send it and then close the RPC
channel. For a graceful shutdown, that doesn't seem ideal. We should at least
wait a bit for the RPC message to be sent before shutting things down. I ran
some tests locally and its pretty easy to hit a situation where the error
message doesn't even get sent to the {{SparkClientImpl}}
