Commit 34f2384ea66a4b62627cb5a3ff3544b6d4558469 in asterixdb's branch refs/heads/master from
[~buyingyi]
[ https://git-wip-us.apache.org/repos/asf?p=asterixdb.git;h=34f2384 ]

ASTERIXDB-1791, ASTERIXDB-1796: fix failure handling in runtime operators.

This change includes the following parts:
- Fix the implementation of fail() and close() in several runtime operators
  to avoid file handle leak and job hang;
- Add an erase method to RunFileWriter which closes files before deleting
  them in order release the holding disk space;
- Call RunFileWriter.close() and RunFileReader.close() in "finally" blocks.
- Fix RunFileReader to not truncate files to be deleted - it is not the root
  cause of un-released disk space - open deleted files are the root cuase;
- Check file handle leaks in LangExecutionUtil.tearDown().
