FYI, looks like this patch broke -Phadoop-1 compilation compatibility. I've opened HIVE-10536
for this.

> This issue proposes to consolidate several Hive calls to the Hadoop Common {{FileSystem}}
API into a fewer number of calls that still accomplish the equivalent work.  {{FileSystem}}
API calls typically translate into RPCs to other services like the HDFS NameNode or alternative
file system implementations.  Consolidating RPCs will lower latency a bit for Hive code and
reduce some load on these external services.
