Sahil Takiar commented on HIVE-18766: ------------------------------------- Few minor comments, overall LGTM: * Line 138 of {{RemoteDriver}} is already creating a {{RpcConfiguration}} object, so no need to create another one for {{getFutureTimeoutMs}} * Instead of swallowing an exception from {{sendError}} can we just log it at WARN level > 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 > Assignee: Aihua Xu > Priority: Major > Attachments: HIVE-18766.1.patch > > > 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}} -- This message was sent by Atlassian JIRA (v7.6.3#76005)
