Can't kill a job which contains a while loop in the main method before it be submitted

[XiangWei Huang]

Hi,
I met a problem when use jedis in flink.When using jedis to get a connection to 
redis  if the redis server is not available then jedis will keep trying and 
never end,the problem is that the job’s status is not set to RUNNING by flink, 
that means it can’t be killed by flink.The only way to break this look is to 
restart jobmanager.
Is there another way to solve this without restart jobmanager.
