我正在尝试在hive中处理多字符delmiter。
我已经创建了一个成功相同的表
create external table showtmp3(doc_name STRING,doc_content STRING) row format SERDE 'org.apache.hadoop.hive.serde2.MultiDelimitSerDe' WITH SERDEPROPERTIES ('field.delim'='#a#') location '/unmesha/OUT';
然后我需要发出如下查询。
INSERT OVERWRITE DIRECTORY '/unmesha/OUT_tmpShowData' SELECT * showtmp3 limit 10;
但它给了我下面的错误

我应该下载任何jar并放入某个位置吗?
请建议
答案 0 :(得分:1)
您可以从Maven repo下载原始 jar :https://mvnrepository.com/artifact/org.apache.hive/hive-contrib/0.14.0
下载此jar文件并将其放入群集中所有节点的hive / lib 文件夹中。这应解决问题
答案 1 :(得分:0)
您必须将hive-contrib.jar文件添加到配置单元。在蜂巢壳中运行以下命令。
add JAR /opt/cloudera/parcels/CDH <version> /jars/hive-contrib.jar
(or)
add jar /usr/lib/hive/lib/hive-contrib-<version>.jar;
