             Summary: Guaranteed NPE in DDLSemanticAnalyzer
                 Key: HIVE-8579
                 URL: https://issues.apache.org/jira/browse/HIVE-8579
             Project: Hive
          Issue Type: Bug
            Reporter: Lars Francke


This was added by [~jdere] in HIVE-8411. I don't fully understand the code (i.e. what it means when desc is null) but I'm sure, Jason, you can fix it without much trouble?

{code}
if (desc == null || !AlterTableDesc.doesAlterTableTypeSupportPartialPartitionSpec(desc.getOp())) {
  throw new SemanticException( ErrorMsg.ALTER_TABLE_TYPE_PARTIAL_PARTITION_SPEC_NO_SUPPORTED, desc.getOp().name());
        } else if (!conf.getBoolVar(HiveConf.ConfVars.DYNAMICPARTITIONING)) {
          throw new SemanticException(ErrorMsg.DYNAMIC_PARTITION_DISABLED);
        }
{code}

You check for whether {{desc}} is null but then use it to do {{desc.getOp()}}.
