Summary: org.apache.geode.InternalGemFireError: ERROR: Assertion
failed
Key: GEODE-7728
URL: https://issues.apache.org/jira/browse/GEODE-7728
Project: Geode
Issue Type: Bug
Components: querying
Reporter: Juan Ramos
When trying to run a simple equi-join query (both fields are indexed) with
additional filters on a single region, the execution fails with the following
exception:
{noformat}
org.apache.geode.InternalGemFireError: ERROR: Assertion failed: ' '

{noformat}
The problem seems to be that, in order to optimise the execution for a more
general form of join queries, we fail to find the "optimal" filter on which to
operate and, thus, the exception is thrown.
The problem is not reproducible whenever one of the fields used for the
comparison is not indexed, or when both indexes are passed to the query engine
using the *HINT* keyword.
