hive中创建子表并插入数据过程初始化MR报错解决方法

本文继成上一篇通过hive分析nginx日志文章，详情参考下面链接：

http://www.cnblogs.com/wcwen1990/p/7066230.html

接着来：

创建业务子表：

drop table if exists chavin.nginx_access_log_comm;

create table if not exists chavin.nginx_access_log_comm(

host STRING,

time STRING,

request STRING,

referer STRING

)

row format delimited fields terminated by '\t'

STORED AS orc tblproperties("orc.compress"="SNAPPY");

insert into chavin.nginx_access_log_comm select host,time,request,referer from chavin.nginx_access_log;

结果报错如下：

hive (default)> insert into chavin.nginx_access_log_comm select host,time,request,referer from chavin.nginx_access_log;

hive (default)>

从日志看，貌似执行mr因为缺少包而导致的故障。

解决办法：向hive命令行中添加hive-contrib-1.1.0-cdh5.9.2.jar包：

hive (chavin)> add jar /opt/cloudera/parcels/CDH/lib/hive/lib/hive-contrib-1.1.0-cdh5.9.2.jar;

Added [/opt/cloudera/parcels/CDH/lib/hive/lib/hive-contrib-1.1.0-cdh5.9.2.jar] to class path

Added resources: [/opt/cloudera/parcels/CDH/lib/hive/lib/hive-contrib-1.1.0-cdh5.9.2.jar]

再次运行加载数据命令：

hive (chavin)>insert into chavin.nginx_access_log_comm select host,time,request,referer from chavin.nginx_access_log;

问题解决，但是该解决方法只能对本次Hive会话有用，Hive使用命令exit退出后再进入依旧会出现该问题。
