update geometry.odbctest set salary = 50000 employeeid = 10;

sql> update geometry.odbctest set salary = 50000 employeeid = 10;

[s1000][cloudera][hiveodbc] (55) insert operation not support table: hive.geometry.odbctest

[isql]error: not sqlprepare

delete:

when trying delete following error getting

delete geometry.odbctest employeeid=10;

sql> delete geometry.odbctest employeeid=10;

[s1000][cloudera][hiveodbc] (55) insert operation not support table: hive.geometry.odbctest

[isql]error: not sqlprepare

can me out,

you have done couple of required steps properly:

  • orc format
  • bucketed table

a cause be: 1 or more of following hive settings not included:

these configuration parameters must set appropriately turn on transaction support in hive:

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 (for 1 instance of thrift metastore service) hive.compactor.worker.threads – positive number on @ least 1 instance of thrift metastore service

the full requirements transaction support here: https://cwiki.apache.org/confluence/display/hive/hive+transactions

if have verified above settings in place 

describe extended odbctest;

to evaluate transaction related characteristics.
