Hi All,
I know probably this should not post here. I posted it in the user maillist
without any response, so I moved it here. Thanks in advance for any help.
I am trying to use the new transaction feature in Hive-0.14. According to its
document, every transaction table have a base directory and one delta directory
for each transaction in HDFS for data storage. But I can not find the base
directory under the datawarehouse directory in HDFS, there is only delta
directories. Even the initial data is stored in a delta directory. Following is
the commands I used.
create table test_txn (id int ,name string ) clustered by (id) into 2 buckets
stored as orc TBLPROPERTIES('transactional'='true');
insert into table test_txn select * from test_text;
update test_txn set name="liu" where id = 10;
P.S. I have configured the parameters required by the transaction feature:
hive.support.concurrency,
hive.enforce.bucketing,
hive.exec.dynamic.partition.mode,
hive.txn.manager,
hive.compactor.initiator.on
hive.compactor.worker.threads.
Although I cannot find the base directory in HDFS, all SELECT, UPDATE and
DELETE statements works fine and the data in the table is correct. I am
wondering where the base directory is.
Any help is appreciated.
Thanks,
Wantao
