Unable to update Hive Transactional table

Question

I am trying to update Hive Transactional table but its giving below error:

FAILED: SemanticException [Error 10290]: Encountered parse error while parsing rewritten merge/update or delete query.

Below is my table DDL:

CREATE TABLE bucketed_poc(
Col1 Int,
Col2 Int
)
CLUSTERED BY (Col2) INTO 10 BUCKETS
STORED AS ORC TBLPROPERTIES("transactional"="true","orc.compress"="ZLIB");

Below are the properties I have set for ACID table:

set hive.enforce.bucketing = true;
set hive.support.concurrency = true;
set hive.exec.dynamic.partition.mode = nonstrict;
set hive.txn.manager = org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;
set hive.compactor.initiator.on = true;
set hive.compactor.worker.threads = 1;

I am able to delete the data but update is not working. I am running below mentioned Update query:

Update bucketed_poc set col2 = 1 where `col1=877639`; 

Answer 1

In hive transaction tables you cannot update the bucketed column. In your case bucketing is done on col2 column, hence you cannot update the col2.
