Date Fri, 16 Feb 2018 20:52:00 GMT

     [ https://issues.apache.org/jira/browse/HIVE-18735?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eugene Koifman updated HIVE-18735:
----------------------------------
    Description: 
{noformat}
create table T1(a int, b int) clustered by (a) into 2 buckets stored as orc TBLPROPERTIES
('transactional'='true')";

create table T like T1;

show create table T ;

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
 'file:/Users/ekoifman/IdeaProjects/hive/ql/target/tmp/org.apache.hadoop.hive.ql.TestTxnCommands-1518813536099/warehouse/t'
TBLPROPERTIES (
  'transient_lastDdlTime'='1518813564')
{noformat}

Specifying props explicitly does work
