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