Issue: "Stored As" field mapping improvement
This issue is related to Issue #13791

1] For Storage Format- TEXTFILE  
a]  Currently ADS uses, below mapping:

b] Mapping should be

InputFormat:       org.apache.hadoop.mapred.TextInputFormat,
OutputFormat:    org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat


Reason:  OutputFormat:     " org.apache.hadoop.hive.ql.io.IgnoreKeyTextOutputFormat "    is deprecated.
This is not updated in Hive confluence Language manual . 

Found correct information from Hive Java Docs [Deprecated Classes]- Ref.Link1 [Hive 0.10]   Link2 [Hive 1.2.1]
Link Summarizes to below text

iv] Output of  command [desc extended testseq] also matches with above Input and Output format, still Stored As field is not reflected properly.
As this Input and Output format is mapped to SEQUENCEFILE, it should be displayed in Stored As field.
