+#### 13. 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.
