Subject [jira] [Commented] (PHOENIX-3757) System mutex table not being created in SYSTEM namespace when namespace mapping is enabled
Date Tue, 26 Sep 2017 02:30:00 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-3757?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16180105#comment-16180105

Josh Elser commented on PHOENIX-3757:
-------------------------------------

[~karanmehta93], go for it!

I honestly don't remember - I'd have to refresh myself, it's been so long.

I recall Samarth had asked to try to change the IT's base class. I was worried not using a
fresh HBase cluster would result in us not actually testing what we think we're testing (if
the system tables exists or the PhoenixDriver has any cached info). This requires some insight.

I think Ankit had some edge cases which I wasn't correctly handling -- JIRA will serve as
a better record than my memory for sure.

> Noticed this issue while writing a test for PHOENIX-3756:
> The SYSTEM.MUTEX table is always created in the default namespace, even when {{phoenix.schema.isNamespaceMappingEnabled=true}}.
At a glance, it looks like the logic for the other system tables isn't applied to the mutex
table.
