----------------------------------------
Summary: MetadataCycleException not handled in
VolcanoRelMetadataProvider
Key: CALCITE-2751
URL: https://issues.apache.org/jira/browse/CALCITE-2751
Project: Calcite
Issue Type: Bug
Components: core
Reporter: Steven Phillips
Assignee: Julian Hyde
If the RelSubset has no best RelNode, we iterate through all of the RelNodes
until we find one that has appropriate Metadata. But if the RelNode we choose
has already been visited, the CyclicMetadataException is thrown, but not
caught. We should catch the exception and try again on another RelNode.
