Description

When using other file system other than hdfs, users see warning message regarding hdfs chgrp. The warning is very annoying and confusing. We'd better remove it.
The warning example:

hive> insert overwrite table s3_test select total_emp, salary, description from sample_07 limit 5;
-chgrp: '' does not match expected pattern for group
Usage: hadoop fs [generic options] -chgrp [-R] GROUP PATH...
Total jobs = 1
Launching Job 1 out of 1
Number of reduce tasks determined at compile time: 1
In order to change the average load for a reducer (in bytes):
  set hive.exec.reducers.bytes.per.reducer=<number>
