--------------------------------
Summary: Tone down scary executor lost messages when killing on
purpose
Key: SPARK-4134
URL: https://issues.apache.org/jira/browse/SPARK-4134
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.2.0
Reporter: Andrew Or
Assignee: Andrew Or
After SPARK-3822 goes in, we are now able to dynamically kill executors after
an application has started. However, when we do that we get a ton of scary
error messages telling us that we've done wrong somehow. It would be good to
detect when this is the case and prevent these messages from surfacing.
This maybe difficult, however, because the connection manager tends to be quite
verbose in unconditionally logging disconnection messages. This is a very
nice-to-have for 1.2 but certainly not a blocker.
