What kind of data be left in ‘kylin.env.hdfs-working-dir’ ? We often > execute kylin cleanup storage command, but now our working dir folder is > about 300 GB size, can we delete old data manually? > > - The data in ‘hdfs-working-dir’ (‘hdfs:///kylin/kylin_metadata/’ > by default) includes intermediate files (will be GC) and Cuboid data (won’t > be GC). The Cuboid data is kept for the further segments’ merge, as Kylin > couldn’t merge from HBase. If you’re sure those segments won’t be merged, > you can move them to other paths or even delete. > - Please pay attention to the “resources” sub-folder under > ‘hdfs-working-dir’, which persists some big metadata files like > dictionaries and lookup tables’ snapshots. They shouldn’t be moved. > > 杨冠军 <champion.y...@kutesmart.com> 于2018年11月1日周四 上午9:10写道： > > 您好： > kylin构建完成后，会在hbase中产生很多文件，附件中为生成的文件截图，请问这些文件哪些可以删除？ > 谢谢！ > > *杨冠军* 开发工程师 > * champion.y...@kutesmart.com <champion.y...@kutesmart.com> * > *公司名称：青岛酷特智能股份有限公司* > 地址：即墨市红领大街17号 > 电话： > 手机：15563907071 > -- Regards!
