      Description

      In case where user loads data into table using overwrite, using a different file, it is not being overwritten.

      $ hdfs dfs -cat /tmp/data
      aaa
      bbb
      ccc
      $ hdfs dfs -cat /tmp/data2
      ddd
      eee
      fff
      $ hive
      hive> create table test (id string); 
      hive> load data inpath '/tmp/data' overwrite into table test;
      hive> select * from test;
      aaa
      bbb
      ccc
      hive> load data inpath '/tmp/data2' overwrite into table test;
      hive> select * from test;
      aaa
      bbb
      ccc
      ddd
      eee
      fff
      

      It seems it is broken by HIVE-3756 which added another condition to whether "rmr" should be run on old directory, and skips in this case.

      There is a workaround of set fs.hdfs.impl.disable.cache=true;
      which sabotages this condition, but this condition should be removed in long-term.
