> In case where user loads data into table using overwrite, using a different
> file, it is not being overwritten.
> {code}
> $ 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;

> 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.
