CDH5.4.10 在Hive上执行Update,Delete操作报错Attempt to do update or delete using transaction manager that doe

在Hive上执行事务操作(增、删、改、查)出现FAILED: SemanticException [Error 10294]: Attempt to do update or delete using transaction manager that does not support these operations.错误

已被周知的是Hive从0.14版开始支持事务操作，而CDH5.4.10总的Hive是1.1.0版本，而且该配置的也都配置了，如

SET hive.support.concurrency=true;

SET hive.enforce.bucketing=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;

set hive.compactor.worker.threads = 1 ; update abc1 SET empwork_name = "Raj" where empwork_key = 70;"

还有把表建成orc格式，增加bucket

create table testTableNew(id int ,name string ) clustered by (id) into 2 buckets stored as orc TBLPROPERTIES('transactional'='true');

但问题依旧没有解决

后来搜了下Cloudera的官方论坛，有个方案是在hive运行时配置事务操作，例如

hive -e "set hive.auto.convert.join.noconditionaltask.size = 10000000; set hive.support.concurrency = true; set hive.enforce.bucketing = 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;

解决问题，原因是Hive事务管理器（ transaction manager ）不支持设置为每条Query级别的，而是应该是Session级别的
