shijinkui commented on FLINK-5166:
----------------------------------
Debug, found that:
there four tmp file in the `expectedFiles` list, as there are two file in
`paths`, so when execute
`assertTrue(expectedFiles.get(i).equals(paths.get(i)));`, get null by the
index.
tmp file such as:
flink/flink-java/tmp/first/TextInputFormatTest3439492861909451525.tmp
It's strangely when i delete the tmp files, then run the test, it's ok.
I think we can clear the directory before test. I add two line code in the PR.
