Vaibhav Gumashta commented on HIVE-6741:
----------------------------------------
[~prasadm] Sure, we can wait. However, the problem will manifest whenever we
upgrade so I thought fixing it sooner is no harm. But since 13 won't be using
hadoop 2.4, let me tag this for 14.
[~thejas] Had chat with hadoop folks, and it seems they won't revert the
change. Check the logic for the change in this comment:

> [HADOOP-10211|https://issues.apache.org/jira/browse/HADOOP-10211] made a
> backward incompatible change due to which the following hive call returns a
> null map
> ([HiveAuthFactory-old|https://github.com/apache/hive/blob/fc3fdb19668369c56994d11df3207e14f2c5dba8/service/src/java/org/apache/hive/service/auth/HiveAuthFactory.java#L115]):
> {code}
> Map<String, String> hadoopSaslProps = ShimLoader.getHadoopThriftAuthBridge().

> Since this code path is only used for logging hadoop sasl qop values in case
> hadoop's qop > hive's qop, we can do away with this and add a general log
