             Summary: [Standalone] Master registers application again when driver relaunched
                 Key: SPARK-19900
                 URL: https://issues.apache.org/jira/browse/SPARK-19900
             Project: Spark
          Issue Type: Bug
          Components: Deploy, Spark Core
    Affects Versions: 1.6.2
         Environment: Centos 6.5, spark standalone
            Reporter: Sergey


I've found some problems when node, where driver is running, has unstable network. A situation is possible when two identical applications are running on a cluster.

*Steps to Reproduce:*
# prepare 3 node. One for the spark master and two for the spark workers.
# submit an application with parameter spark.driver.supervise = true
# go to the node where driver is running (for example spark-worker-1) and close 7077 port
{code}
# iptables -A OUTPUT -p tcp --dport 7077 -j DROP
{code}
# wait more 60 seconds
# look at the spark master UI
There are two spark applications and one driver. The new application has WAITING state and the second application has RUNNING state. Driver has RUNNING or RELAUNCHING state (It depends on the resources available, as I understand it) and it launched on other node (for example spark-worker-2)
# open the port
{code}
# iptables -D OUTPUT -p tcp --dport 7077 -j DROP
{code}
# look an the spark UI again
There are no changes
