Hi,

After seeing your mail, i came to know that you are trying to update and
delete operations on Hive 1.0.

For doing the same,

After extracting Hive version, you have to create Hive meta store

http://www.cloudera.com/content/cloudera/en/documentation/cdh5/v5-1-x/CDH5-Installation-Guide/cdh5ig_hive_metastore_configure.html

Then in hive-site.xml, you need set the new parameters like

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

Then restart Hive-server and Metastore

Now create one normal table and one external table with orc format

and load from normal to orc table

Now you can update and delete records.

Let me know any concerns.

*Thanks & Regards,*
