Ayush Saxena commented on HIVE-26488:
-------------------------------------
The bug triggers due to Reflection, One reason being if some appication brings
in a higher version of Relections into the classpath, which happened in case
with me while trying to integrate with Ozone, Can not have a lower version of
Reflections 0.9.12, because of Guava conflicts. Reflections ditches Guava post
0.9.12 only.
Second, I observed this in a customer issue, where they were executing the
queries through a JAR, and they were facing the same NPE.
It looks some what like this issue, but not exactly the same one:
[https://github.com/ronmamo/reflections/issues/373]
The customer got away from using their custom jar to beeline query script, so
the env & the custom jar repro isn't with me to retry. But the NPE can be
reproduced, by just moving reflections to 0.9.12 and then running
TestMetaStoreMetrics
