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.
