Sean Owen updated SPARK-6924:
-----------------------------
Priority: Minor (was: Major)
> driver hangs when net is broken
> -------------------------------
>
> Key: SPARK-6924
> URL: https://issues.apache.org/jira/browse/SPARK-6924
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Reporter: xukun
> Priority: Minor
>
> In yarn-client mode, client is deployed out side of cluster. When the net
> between client and cluster is broken, driver lost all executors. In normal
> situation, client returns and app fails. Actually, the driver hangs, user do
> not know whether app is ok. So we should let driver return not hang.
> The solution: in HeartbeatReceiver thread, check whether some executor send
> heartbeat to dirver at the fixed rate. If no execuor send heartbeats to
> driver, close SparkContext.
