Brahma Reddy Battula commented on HDFS-13972:
---------------------------------------------
{quote} As per the change this is ONLY for getDatanodeReport.
{quote}
IMO, {{RouterRpcServer.getRemoteUser()}} can be replaced with
{{UserGroupInformation.getCurrentUser()}}.Anyway handler will get [remote
user|https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/ipc/Server.java#L2826]
and execute. we can change for invokeSingle(..), invokeConcurrent(..) and
invokeSequential(..) .
The fix [^HDFS-13972-HDFS-13891.011.patch] is not proper,as this is not
specific to client protocol(generic).Later if we found some other API again we
need to filter.
