Description

CTTAS on temporary micromanaged table does not write data. 

I.e., "SELECT * FROM ctas0_mm;" does not return any rows from the below script:

 

set hive.mapred.mode=nonstrict;

set hive.explain.user=false;

set hive.fetch.task.conversion=none;

set tez.grouping.min-size=1;

set tez.grouping.max-size=2;

set hive.exec.dynamic.partition.mode=nonstrict;

set hive.support.concurrency=true;

set hive.txn.manager=org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;

 

drop table intermediate;

create table intermediate(key int) partitioned by (p int) stored as orc;

insert into table intermediate partition(p='455') select distinct key from src where key >= 0 order by key desc limit 2;

insert into table intermediate partition(p='456') select distinct key from src where key is not null order by key asc limit 2;

insert into table intermediate partition(p='457') select distinct key from src where key >= 100 order by key asc limit 2;

  

drop table ctas0_mm; 

explain create temporary table ctas0_mm tblproperties ("transactional"="true", "transactional_properties"="insert_only") as select * from intermediate;

create temporary table ctas0_mm tblproperties ("transactional"="true", "transactional_properties"="insert_only") as select * from intermediate;

 

select * from ctas0_mm;

drop table ctas0_mm;

drop table intermediate;
