Demyd updated HIVE-23879:
-------------------------
Description:
When I alter location for not empty table and inserts data to it. I don't see
old data at work with hs2. But I can find there in maprfs by old table location.
Steps to reproduce:
{code:sql}
1. connect to hs2 by beeline"
hive --service beeline -u "jdbc:hive2://<fqdn>:10000/;"
2. create test db:
create database dbtest1 location 'hdfs:///dbtest1.db';
3. create test table:
create table dbtest1.t1 (id int);
4. insert data to table:
insert into dbtest1.t1 (id) values (1);
5. set new table location:
alter table dbtest1.t1 set location 'hdfs:///dbtest1a/t1';
6. insert data to table:
insert into dbtest1.t1 (id) values (2);
{code}
Actual result:
{code:sql}
jdbc:hive2://<dqdn>:> select * from dbtest1.t1;
+--------+
|t1.id |
+--------+
|2 |
+--------+
1 row selected (0.097 seconds)
{code}
Expected result:
{code:sql}
jdbc:hive2://<dqdn>:> select * from dbtest1.t1;
+--------+
|t1.id |
+--------+
|2 |
+--------+
|1 |
+--------+
1 row selected (0.097 seconds)
