@liancheng This is to port HIVE-7620 into spark to solve hadoop
incompatibility issue. It will replace the getHadoopSaslProperties in
org.apache.hadoop.hive.thrift.HadoopThriftAuthBridge20S if necessary by
checking the hadoop version.
https://issues.apache.org/jira/browse/HIVE-7620
I agree the code may not be fitting into the overall code base. But it is
broken in hive-0.13 connecting to secure cluster hadoop-2.5 and beyond due to
this issue. If hive-0.14 will be supported soon, this patch may not be critical.
By the way, hadoop-2.6 and beyond is becoming main stream in my point of
view.
