Kettle日志中BootFeaturesInstaller错误

到新公司接手了别人的Kettle ETL作业。

发现每次启动 Kettle ，日志中都会出现下面的错误，虽然不影响运行结果，但是看着不爽：

　解决方法（公司使用的是 6.1 版本，其他版本没用过）：

修改<pdi_home>/system/karaf/etc/org.apache.karaf.features.cfg

把featuresBoot=config,pentaho-client,pentaho-metaverse,pdi-dataservice,pdi-data-refinery

改成featuresBoot=config,pentaho-client,pentaho-metaverse,pdi-dataservice

然后删除 <pdi_home>/system/karaf/caches目录
