------------------------------------
Summary: Revisit Kerberos login in ConnectionInfo
Key: PHOENIX-7470
URL: https://issues.apache.org/jira/browse/PHOENIX-7470
Project: Phoenix
Issue Type: Bug
Components: core
Reporter: Istvan Toth
Performing Kerberso login in ConnetionInfo causes a performance regression,
which is partially fixed by PHOENIX-7646
We need to check how the kerberos principal is handled in Phoenix.
I strongly suspect that Phoenix won't handle different principals for different
connections in the same JVM. This is not necessarily the problem, but we should
minimize the performance cost of Kerberos logins.
The root of the perf regression is that in order to use the HBase Kerberos
utulity functions for custom principlas, we need to update the Configuration
object.
If we do this in the CQSI object, using the cached Configuration object, then
the performance cost is negligible.
