------------------------------
Summary: Heartbeat-timeout executor is added back and used again
Key: SPARK-24387
URL: https://issues.apache.org/jira/browse/SPARK-24387
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.1.0
Reporter: Rui Li
In our job, when there's only one task and one executor running, the executor's
heartbeat is lost and driver decides to remove it. However, the executor is
added again and the task's retry attempt is scheduled to that executor, almost
immediately after the executor is marked as lost.
