Ashutosh Chauhan commented on HIVE-13705:
-----------------------------------------
According to
https://github.com/apache/hadoop/blob/branch-2.6.0/hadoop-hdfs-project/hadoop-hdfs/src/main/java/org/apache/hadoop/hdfs/protocol/ClientProtocol.java#L458
rename will return false if file already exists. Are you finding that to be
incorrect? I would like to understand thats the case, otherwise proposed
solution *always* makes 2 calls to NN, instead of current solution which does
it only when needed.
