Subject TYPE_NAME col in mysql issue.

Hi All,

I am trying to create a table with a single column as below in hive-2.1.0,

CREATE TABLE sample( data struct<`array`:array<struct<

STORED AS parquet;

But hive throws, FAILED: Execution Error, return code 1 from
org.apache.hadoop.hive.ql.exec.DDLTask. InvalidObjectException(message:Invalid
column type name is too long: struct<.......

I understand the issue, as i have fixed the similar problem in hive 1.2.0
by increasing the TYPE_NAME col size in COLUMNS_V2 table, but the same
doesnt work in hive-2.1.0.
Additionally i have also inserted the same column into the COLUMNS_V2 mysql
metastore table and found out the insert was successful.

Would like to know if there is any workaround, any help is highly
appreciated.

Satyajit.
