> Currently, Create table like support table properties.
> But it doesn't inherit table properties from original table.
> {code}
> create table T1(a int, b int) clustered by (a) into 2 buckets stored as orc TBLPROPERTIES
('comment'='comm');
> create table T like T1;
> show create table T;
>  {code}
> *Output:*
> {code}
> CREATE TABLE `T`(
>   `a` int, 
>   `b` int)
> CLUSTERED BY ( 
>   a) 
> INTO 2 BUCKETS
> ROW FORMAT SERDE 
>   'org.apache.hadoop.hive.ql.io.orc.OrcSerde' 
> STORED AS INPUTFORMAT 
>   'org.apache.hadoop.hive.ql.io.orc.OrcInputFormat' 
> OUTPUTFORMAT 
>   'org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat'
> LOCATION
>   'maprfs:/user/hive/warehouse/t'
> TBLPROPERTIES (
>   'COLUMN_STATS_ACCURATE'='{\"BASIC_STATS\":\"true\"}', 
>   'numFiles'='0', 
>   'numRows'='0', 
>   'rawDataSize'='0', 
>   'totalSize'='0', 
>   'transient_lastDdlTime'='1521230300')
> {code}
> It uses just default table properties and doesn't inherit properties from original table.
> It would be great if create table like will inherit origin table properties and will
override them if they are specified in query .
