Jeff commented on PHOENIX-7290:
-------------------------------
Thanks for the response,
I noticed this same error appeared in this ticket
https://issues.apache.org/jira/browse/PHOENIX-5231 which was introduced since
4.15.
The error is thrown when guidePostsCacheFactory is null when
loadAndGetGuidePostsCacheFactory() is called
[https://github.com/apache/phoenix/blob/5.1.3/phoenix-core/src/main/java/org/apache/phoenix/query/GuidePostsCacheProvider.java#L57]
Here's two error stack, one from SQLSquirrel and another using spring-jdbc
under OSGi framework.
[^spring-jdbc_error_stack.txt]
[^SQLSquirrel_error_stack.txt]
Is there any workaround to resolve this error when using the client jar as a
third-party library?
