Jason Dere commented on HIVE-22709:
-----------------------------------
I think I see what happened - when the method signature of
SemanticAnalyzer.analyzeInternal was changed from
{code}
void analyzeInternal(ASTNode ast, Supplier<PlannerContext> pcf) throws
SemanticException {
{code}
to
{code}
void analyzeInternal(ASTNode astToAnalyze, Supplier<PlannerContext> pcf)
throws SemanticException {
{code}
then in this line:
{code}
lookupInfo = createLookupInfoForQuery(ast);
{code}
"ast" changed from being a method parameter to the SemanticAnalyzer.ast field.
We just need to change that line to lookupInfo =
createLookupInfoForQuery(astToAnalyze);
In fact all references to "ast" in that method will need to be changed to
astToAnalyze since the parameter was renamed, it is unfortunate that
SemanticAnalyzer had an ast field which hid this error.
