Istvan Toth commented on PHOENIX-7290:
--------------------------------------
Thank you.
Looking at the code, the problem seems to be that we DO use
PhoenixContextExecutor in CQSI.init(), but we refer to that class in the
constructor, which is not running inside init().
Looks like this would be fixed by moving the cache initialization into the
init() function.
i.e.
This initialization:
https://github.com/apache/phoenix/blob/afdba89b005cb167fafe8530de750ad297f86d5a/phoenix-core-client/src/main/java/org/apache/phoenix/query/ConnectionQueryServicesImpl.java#L474
should be moved somewhere inside this block:
https://github.com/apache/phoenix/blob/afdba89b005cb167fafe8530de750ad297f86d5a/phoenix-core-client/src/main/java/org/apache/phoenix/query/ConnectionQueryServicesImpl.java#L3560
I don't have the time to work on this now.
Could you make this change and test to see if it fixes the isse [~zidanej] ?
