配置单元acid更新和删除错误

Question

我使用Hive1.2.1和TEZ0.7进行测试，但是当我使用acid表进行更新和删除时，出现了一些问题，下面是表的结构：

CREATE EXTERNAL TABLE IF NOT EXISTS working.dw_items_w
(
column defination
)
CLUSTERED BY (id) into 5000 buckets
STORED AS ORC
LOCATION '/sys/edw/working/dw_items_w2'
TBLPROPERTIES ("transactional"="true");

update working.dw_items_w
set 
PROCESS_FLAG =(case when (
(TGT_LSTG_STATUS_ID = 1 and (to_date(SALE_END) - to_date(TGT_AUCT_END_DT) ) <> 0 )
or  (TGT_LSTG_STATUS_ID in (1,2) and NEW_LSTG_STATUS_ID in (0,4) )   
) then  'D' 
when 
((TGT_LSTG_STATUS_ID =1 and NEW_LSTG_STATUS_ID = 1 and datediff(to_date(SALE_END) ,to_date(TGT_AUCT_END_DT) 
) = 0 )
or (TGT_LSTG_STATUS_ID = 2 and NEW_LSTG_STATUS_ID = 1)) then 'X' else PROCESS_FLAG end ),
NEW_LSTG_STATUS_ID = (case when TGT_LSTG_STATUS_ID = 0  AND NEW_LSTG_STATUS_ID = 0   AND to_date(SALE_END)
 <  date_sub(to_date( from_unixtime(unix_timestamp(),'yyyy-MM-dd') ), 92)
     AND to_date(SALE_END)  <> to_date('1969-12-31') then 1 else NEW_LSTG_STATUS_ID end) 

where PROCESS_FLAG = 'U';

Answer 1

将以下内容添加到hive-site.xml

<property>
    <name>hive.enforce.bucketing</name>
    <value>true</value>
</property>
<property>
    <name>hive.compactor.initiator.on</name>
    <value>true</value>
</property>
<property>
    <name>hive.support.concurrency</name>
    <value>true</value>
</property>
<property>
    <name>hive.compactor.worker.threads</name>
    <value>1</value>
</property>
<property>
    <name>hive.txn.manager</name>
    <value>org.apache.hadoop.hive.ql.lockmgr.DbTxnManager</value>
</property>

然后确保您正在创建一个带有bucketing的ORC表：

如果不存在则创建表foo.tableinfo(schema_name varchar(32)、table_name varchar(64)、department varchar(64)、country varchar(64)、state varchar(64)、city varchar(64)、granularity int、notes varchar(256))由(table_name)聚类到4个存储为ORC TBLPROPERTIES（“ORC.compress”=“zlib”,“transactional”=“true”）的桶中；

则以下操作将起作用：

从foo.tableinfo中删除table_name='foo'；
