> 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 .
