yuqi commented on FLINK-9196:
-----------------------------
As far as i see, The problem may due to the fact that Clifront forget to delete
tmp files that lie in HDFS in normal mode.
As the log says
{code:java}
2018-04-26 17:44:18,049 INFO
org.apache.flink.yarn.AbstractYarnClusterDescriptor - The Flink YARN client has
been started in detached mode. In order to stop Flink on YARN, use the
following command or a YARN web interface to stop it:
yarn application -kill application_1520998295402_0099
Please also note that the temporary files of the YARN session in the home
directory will not be removed.
Job has been submitted with JobID 3c78bf2c36a0ceceea5ae9c497f82732
{code}
I wonder if we should delete tmp file in detached mode.
I make some change as blow.

Can one help to look if this is Ok?
