--------------------------------
Summary: Dynamic allocation: avoid double counting when killing
same executor
Key: SPARK-9795
URL: https://issues.apache.org/jira/browse/SPARK-9795
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.4.0
Reporter: Andrew Or
Assignee: Andrew Or
Priority: Critical
Currently, if we kill the same executor twice in rapid succession, we will
lower the executor target by 2 instead of 1. In cases where we don't re-adjust
the target upwards frequently, this will result in jobs hanging.
This may or may not be the same as SPARK-9745. Until we can verify the
correlation, however, this will remain a separate issue.
