--------------------------------------------------------
Summary: CalcitePlanner.genOpTree tries to run with cbo disable
even after a semantic analysis exception
Key: HIVE-12580
URL: https://issues.apache.org/jira/browse/HIVE-12580
Project: Hive
Issue Type: Bug
Reporter: Hari Sankar Sivarama Subramaniyan
Assignee: Hari Sankar Sivarama Subramaniyan
The following code in CalcitePlanner.genOPTree looks buggy :
{code}
if (!conf.getBoolVar(ConfVars.HIVE_IN_TEST) || isMissingStats
|| e instanceof CalciteSemanticException) {
reAnalyzeAST = true;
} else if (e instanceof SemanticException) {
throw (SemanticException) e;
} else if (e instanceof RuntimeException) {
throw (RuntimeException) e;
} else {
throw new SemanticException(e);
}
{code}
If we have missing stats and a Semantic exception thrown from from the try
block, we still go ahead and continue to generate a plan with cbo turned off.
