Hadoop Hive ACID 查询错误

Question

我在 hadoop 集群上工作，hortonworks 2.4 发行版。 我想对 Hive 表进行 ACID 操作。这是我的声明:

CREATE TABLE myAcidTable (..)
CLUSTERED BY(myKey) INTO 1 BUCKETS
STORED AS ORC TBLPROPERTIES ('transactional'='true','orc.compress'='SNAPPY');

我根据具有相同结构的外部 Hive 表填充此表。

INSERT INTO myAcidTable
SELECT * FROM MyTmpTable;

这个操作效果很好:

Loading data to table MyAcidTable
Table myAcidTable stats: [numFiles=1, numRows=4450, totalSize=42001, rawDataSize=0]
OK

我尝试通过配置单元 shell 查询此表:

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=3;

SELECT * FROM myAcidTable
WHERE myKey = 12;

但我有这个错误(即使状态似乎没问题):

OK
Failed with exception java.io.IOException:java.lang.RuntimeException: serious problem

当我查看日志时，我发现:

org.apache.ambari.view.hive.client.HiveErrorStatusException: H170 Unable to fetch results. java.io.IOException: java.lang.RuntimeException: serious problem

...
Caused by: java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException: delta_0000000_0000000 does not start with base_

这很奇怪，因为当我在没有事务属性的情况下声明我的表时，select 语句运行良好

CREATE TABLE myAcidTable (..)
CLUSTERED BY(myKey) INTO 1 BUCKETS
STORED AS ORC TBLPROPERTIES ('orc.compress'='SNAPPY');

SELECT * FROM myAcidTable
WHERE myKey = 12;

结果:

OK
12 ...

你知道去哪里找吗？感谢您的帮助。

Answer 1

这可能是因为您在创建表或将数据加载到表中时使用了错误的事务管理器。

在我的例子中，我有 org.apache.hadoop.hive.ql.lockmgr.DummyTxnManager

代替 org.apache.hadoop.hive.ql.lockmgr.DbTxnManager

要消除错误，您需要删除表，设置正确的事务管理器即

hive> 设置 hive.txn.manager = org.apache.hadoop.hive.ql.lockmgr.DbTxnManager;

然后重新创建表。
