Shaofeng SHI commented on KYLIN-901:
------------------------------------
A quick way to run this cleanup:
cd $KYLIN_HOME
./bin/metastore.sh clean
This will report the garbage that can be cleaned from metadata store; Take a
backup and then run the clean with delete option:
./bin/metastore.sh backup
./bin/metastore.sh clean --delete=true
> Add tool for cleanup Kylin metadata storage

>
>
> Kylin persists some resources like dictionary, lookup table snapshots in the
> metadata store, and will not cleanup them so far; As time goes on, some
> resources became usless (as the cube segment be dropped or merged) but still
> take space there; Need a tool to cleanup them, just like the
> StorageCleanupJob;
