Brahma Reddy Battula commented on HDFS-12284:
---------------------------------------------
[~elgoiri] thanks for updating the patch. Latest patch lgtm. Pending for
jenkins.
[~daryn] do you have any comments on latest patch..?
bq.I'm not sure if the hostname handling is necessary. You should be able to
replace _HOST in the principal with the intended hostname instead of using
another config key.
As [~lukmajercak] pointed,New config is to support multi-homed environments
where hosts are configured with multiple hostnames in DNS or hosts files(like
DN HADOOP-12437).
AS [~crh] mentioned,ugi caching will done as part connection pool optimisation.
so,can we gohead with commit..?
