-----------------------------------
Summary: Unnecessary UGI proxy user impersonation check
Key: PHOENIX-3175
URL: https://issues.apache.org/jira/browse/PHOENIX-3175
Project: Phoenix
Issue Type: Bug
Reporter: Josh Elser
Assignee: Josh Elser
Fix For: 4.9.0, 4.8.1
While looking at some issues reported by [~jpplayer], we found that some of the
default Hadoop proxyuser configuration properties in core-site.xml weren't
working as intended.
[~devaraj]'s keen eye noticed that PQS was doing an unnecessary UGI ProxyUser
impersonation check.
We can rely on the SPNEGO authentication as the barrier to use PQS, but then
defer to the impersonation check that HBase is already doing as to which PQS
instances are allowed to talk to HBase (defined by core-site.xml).
