Hi,

The supervisor keeps going down and doesn't run giving below errro

java.io.FileNotFoundException: File '/datadrive/hadoop/storm/supervisor/stormdist/WordCount-2-1491988512/stormconf.ser' does not exist at org.apache.storm.shade.org.apache.commons.io.FileUtils.openInputStream(FileUtils.java:292)

For anyone that comes to this from google, as I did, you may also need to remove/backup the /hadoop/storm/supervisor/localstate directory.

It seems this keeps track of what the supervisor is currently running, so if the stormdist folder doesn't exist but there is a record in localstate, it will keep trying to access that file on startup.
