> For tez engine in our cluster, I found some duplicate line, especially tez
> speculation is enabled. In partition dir, I found both 000002_0 and 000002_1
> exist.
> It's a very low probability event. HIVE-10429 has fix some bug about
> interrupt, but some exception was not caught.
> In our cluster, Task receive SIGTERM, then ClientFinalizer(Hadoop Class) was
> called, hdfs client will close. Then will raise exception, but abort may not
> set to true.
> Then removeTempOrDuplicateFiles may fail because of inconsistency, duplicate
> file will retain.
> (Notes: Driver first list dir, then Task commit file, then Driver remove
> duplicate file. It is a inconsistency case)
