关键点:
清理Kettle缓存:
rm -rf /home/user/data-integration/./system/karaf/caches
rm -rf /home/user/data-integration/./system/karaf/data
配置Kettle big data setting:在 Kettle安装目录/data-integration/plugins/pentaho-big-data-plugin/plugin.properties 中找到配置项
active.hadoop.configuration=cdh513
这里的"cdh513"就是 Kettle安装目录/data-integration/plugins/pentaho-big-data-plugin/hadoop-configurations 下的子目录名字, 又称shim, 它相当于hadoop不同版本的驱动
默认有4个shim, 分别对应hadoop的4个发行版, 用哪个就在上述的plugin.properties里配置好
配置shim的Hadoop setting文件:
Kettle安装目录/data-integration/plugins/pentaho-big-data-plugin/hadoop-configurations/cdh513/下6个xml文件, 如core-site.xml, hbase-site.xml, hdfs-site.xml, yarn-site.xml, hive-site.xml, mapred-site.xml
或者直接从集群那里拷贝覆盖.(CDP各组件配置文件路径: Hadoop: /etc/hadoop/conf, hbase: /etc/hbase/conf, hive: /etc/hive/conf)
拷贝jar包:运行kitchen或pan的时候如果报错: no suitable driver found for jdbc:hive2
可以复制一遍jar包到kettle的lib目录下 以及 active shim的lib目录下
CDH的Hive在 /opt/cloudera/parcels/CDH/lib/hive
可以把/opt/cloudera/parcels/CDH/lib/hive/lib下所有hive开头的jar包复制到 Kettle安装目录/data-integration/lib 和 Kettle安装目录/data-integration/plugins/pentaho-big-data-plugin/hadoop-configurations/cdh513/lib
例如(这里假设kettle安装在/opt下, 且当前生效的shim叫cdh513)
cp /opt/cloudera/parcels/CDH/lib/hive/lib/hive*.jar /opt/data-integration/plugins/pentaho-big-data-plugin/hadoop-configurations/cdh513/lib
cp /opt/cloudera/parcels/CDH/lib/hive/lib/hive*.jar /opt/data-integration/lib
然后再清理一遍kettle的缓存, 否则Kettle可能会不识别刚才拷贝的jar文件:
rm -rf /home/fr-renjie.wei/data-integration/./system/karaf/caches
rm -rf /home/fr-renjie.wei/data-integration/./system/karaf/data
No suitable driver found for jdbc:hive2似乎linux上的Kettle本身在调用Hive jar包的过程中有什么bug, 这个问题经常出现, 网上也有很多人问到这个bug.
我遇到情况是, Kitchen调用job会报这个错, pan不会报错.
我的解决办法:
- 清理一次缓存(rm -rf /home/user/data-integration/./system/karaf/caches)
- 运行kitchen
还有一个一劳永逸的办法, 直接改Kitchen.sh, 加上rm这句
