    HAWQ-376. Fixed QE core dump at HdfsCloseFile() when run stress test …

    …with COPY
    The root cause of this defect is:
    When the master got some error, it will send signal SIGABRT to all segments and then rollback
all works done by all segments. If the segment node haven't finished processing SIGABRT before
the master finishing rollback, all segfile created at this segment is deleted at master node
in fact. So it will report warning to close/delete that hdfs file. We should clean up hdfs
file cache before calling HdfsCloseFile(), so that we will skip second call of HdfsCloseFile()
at ShutdownPostgres().
