[SPARK-15286] [SQL] Make the output readable for EXPLAIN CREATE TABLE and DESC EXTENDED #### What changes were proposed in this pull request? Before this PR, the output of EXPLAIN of following SQL is like ```SQL CREATE EXTERNAL TABLE extTable_with_partitions (key INT, value STRING) PARTITIONED BY (ds STRING, hr STRING) LOCATION '/private/var/folders/4b/sgmfldk15js406vk7lw5llzw0000gn/T/spark-b39a6185-8981-403b-a4aa-36fb2f4ca8a9' ``` `ExecutedCommand CreateTable CatalogTable(``extTable_with_partitions``,CatalogTableType(EXTERNAL),CatalogStorageFormat(Some(/private/var/folders/4b/sgmfldk15js406vk7lw5llzw0000gn/T/spark-dd234718-e85d-4c5a-8353-8f1834ac0323),Some(org.apache.hadoop.mapred.TextInputFormat),Some(org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat),None,false,Map()),List(CatalogColumn(key,int,true,None), CatalogColumn(value,string,true,None), CatalogColumn(ds,string,true,None), CatalogColumn(hr,string,true,None)),List(ds, hr),List(),List(),-1,,1463026413544,-1,Map(),None,None,None), false` After this PR, the output is like `ExecutedCommand CreateTable CatalogTable(Table:extTable_with_partitions, Database:null, Owner:, Create Time:Wed May 11 21:05:06 PDT 2016, Last Access Time:Wed Dec 31 15:59:59 PST 1969, Location:/private/var/folders/4b/sgmfldk15js406vk7lw5llzw0000gn/T/spark-d5d9cbc4-5c20-4c52-b2a7-84c03ca6bc7d, Table Type:EXTERNAL, Schema:[Column(name:key, dataType:int, nullable:Yes, comment:null), Column(name:value, dataType:string, nullable:Yes, comment:null), Column(name:ds, dataType:string, nullable:Yes, comment:null), Column(name:hr, dataType:string, nullable:Yes, comment:null)], Partition Columns:[ds, hr], Num Buckets:-1, Bucket Columns:[], Sort Columns:[], View Original Text:null, View Text:null, Comment:null, Table Parameters:[], Storage Information(Location:/private/var/folders/4b/sgmfldk15js406vk7lw5llzw0000gn/T/spark-d5d9cbc4-5c20-4c52-b2a7-84c03ca6bc7d, InputFormat:org.apache.hadoop.mapred.TextInputFormat, OutputFormat:org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat, Compre ssed:No, Storage Desc Library:null, Storage Desc Parameter:[])), false` This is also applicable to DESC EXTENDED. However, this does not have special handling for Data Source Tables. If needed, we need to move the logics of `DDLUtil`. Let me know if we should do it in this PR.
