Hdfs Federation: The BPOfferService must always connect to namenode as the
login user.
--------------------------------------------------------------------------------------
Key: HDFS-1755
URL: https://issues.apache.org/jira/browse/HDFS-1755
Project: Hadoop HDFS
Issue Type: Sub-task
Affects Versions: Federation Branch
Reporter: Jitendra Nath Pandey
Assignee: Jitendra Nath Pandey
Fix For: Federation Branch
The BPOfferService thread when started, normally connects to the namenode as
the login user. But in case of refreshNamenodes a new BPOfferService may be
started in the context of an rpc call where the user is dfsadmin. In such a
case the connection to the namenode will fail.
