Review comment:
Please don't use long methods like this at ddl. Instead cut it to 3
different methods, similar to getPartitionSpecs, each retrieving one data,
returning it to analyzeInternal. Also please don't use setters at
ShowPartitionDesc, a desc object at ddl should have final variables set at the
constructor, and not by setters. This declares that they may not change later.
Thanks.
