Hadoop 具有动态分区的配置单元插入查询

我有一个orc格式的分区和集群配置单元表，我必须从临时表中插入数据

创建表语句： orc表：

CREATE EXTERNAL TABLE DYN_TGT_TABLE(ID INT,USRNAME VARCHAR(20), LD TIMESTAMP) PARTITIONED BY (PART VARCHAR(20)) CLUSTERED BY (id) INTO 1024 BUCKETS ROW FORMAT SERDE 'org.apache.hadoop.hive.ql.io.orc.OrcSerde' STORED AS INPUTFORMAT 'org.apache.hadoop.hive.ql.io.orc.OrcInputFormat' OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat' LOCATION '/tmp/dyn_tgt_table' TBLPROPERTIES ('transactional'='true','transient_lastDdlTime'='1461157247');

temp table:
CREATE EXTERNAL TABLE DYN_TEMP_TABLE(ID INT,USRNAME VARCHAR(20),PART VARCHAR(20), LD TIMESTAMP) ROW FORMAT DELIMITED FIELDS TERMINATED BY '|' STORED AS TEXTFILE LOCATION '/tmp/dyn_temp_table' TBLPROPERTIES ('transactional'='TRUE','transient_lastDdlTime'='1461216088');

在临时表中添加了5条记录： 蜂巢>

从动态温度表中选择*
嗯

所用时间：0.166秒，获取：5行

以下动态插入查询出错：

insert into TABLE DYN_TGT_TABLE PARTITION(part) select id,usrname,ld,part from DYN_TEMP_TABLE;

错误消息：
此任务的诊断消息：
错误：java.lang.RuntimeException:org.apache.hadoop.hive.ql.metadata.HiveException:hive运行时处理行时出错（标记=0）

请帮助我指出此错误的原因。
请尝试插入覆盖表…对于实现AcidOutputFormat的OutputFormat，不允许插入覆盖表。所以它对ORC表不起作用。我可以通过将存储桶的数量从1024个减少到256个（512个也起作用）来解决这个问题。但我没有找到问题的根源。其他信息：当存储桶设置为1024时，我的群集上只启动了512个还原程序。请尝试插入覆盖表…实现AcidOutputFormat的OutputFormat不允许插入覆盖表。所以它对ORC表不起作用。我可以通过将存储桶的数量从1024个减少到256个（512个也起作用）来解决这个问题。但我没有找到问题的根源。附加信息：当bucket设置为1024时，我的集群上只启动了512个reducer。
