Joe Skora commented on NIFI-2759:
---------------------------------
I think this is timing related. I noticed that the test fails when running the
project test suite, but that if running just for the
{{nifi-standard-processors}} module it passes. It may just need adjustment of
the refresh interval or sleep period in the test.
> TestListDatabaseTables.testListTablesMultipleRefresh consistently failing
