Subject [jira] [Created] (PHOENIX-5366) Perform splittable SYSCAT actions on the client only
Date Mon, 24 Jun 2019 02:30:00 GMT
Lars Hofhansl created PHOENIX-5366:
--------------------------------------

             Summary: Perform splittable SYSCAT actions on the client only
                 Key: PHOENIX-5366
                 URL: https://issues.apache.org/jira/browse/PHOENIX-5366
             Project: Phoenix
          Issue Type: Bug
            Reporter: Lars Hofhansl


With Splittable Syscat we reintroduced new server-to-server communication. We should this
all from the client. [~tdsilva].

Also, sometimes when I run tests they hang. In that case the logs are filled with exceptions
like these:
