------------------------------------------
Summary: Invalid check on an ASTNode#toStringTree in CalcitePlanner
Key: HIVE-14226
URL: https://issues.apache.org/jira/browse/HIVE-14226
Project: Hive
Issue Type: Bug
Reporter: Barna Zsombor Klara
Priority: Minor
The patch for HIVE-12590 has modified the string tree representation of an
ASTNode, so that everything except string literals are now lowercase.
However CalcitePlanner#genSelectLogicalPlan is still checking the occurrence of
an uppercase TOK_FUNCTIONDI constant in the string tree.
(Line 2997 in CalcitePlanner on master)
I think this check will never evaluate to true, so we should either be using a
lowercase String, or remove the check if it is unnecessary.
