> Project: Hive

> Here is related code:
> {code}
> if (desc == null
> ||
> !AlterTableDesc.doesAlterTableTypeSupportPartialPartitionSpec(desc.getOp())) {
> throw new SemanticException(
> ErrorMsg.ALTER_TABLE_TYPE_PARTIAL_PARTITION_SPEC_NO_SUPPORTED,
> desc.getOp().name());
> {code}
> If desc is null, the construction of SemanticException would trigger NPE due
> to the call to desc.getOp().
