Matthias commented on FLINK-21786:
----------------------------------
Could it be that you're writing to a file that already exists but have
overwriting disabled?
As [~f.pompermaier] already mentioned it looks like there is some permission
issue due to the IOException being the original cause. The file you specified
through {{file:///persistent/flinkData/wordcount_out}} could not be created.
> sample Job execution failed
