Yeah I have checked it was a bug , because I used hbase namespace “kylin” with
the patch
"https://issues.apache.org/jira/secure/attachment/12885320/KYLIN-2846-001.patch”
And I modified the code as below and it works well:
MOMO@MOMOdeMacBook-Pro-5:~/gitworkspace/kylin2.0/kylin/dist/apache-kylin-2.1.0-bin/tool$
git diff

Hi yaowu,
The StorageCleanupJob will delete the hbase tables that has no reference; If
you found it didn't work, please check the output log of that command. It
should say something.

这个我看了,执行之后发现只是删除了 hive 中间表 kylin_intermediate_* 任务失败遗留的中间表 和
hdfs://nameservice1:8020/kylin/kylin-kylin_metadata/ 目录下没用的临时目录，
hbase 里的 segment 表仍然存在的

主题: kylin drop cube segment Htable 仍然存在
嗨，all ，在清理没用的cube （kylin2.1.0) 时，发现cube 被purge和drop 之后，对应的segment hbase 表仍然在
base中存在，只是在kylinmeta 表的里的元信息被清除， 这是我的特例还是为了数据安全特意让他存在，
只能人工删除相关的表呢？
Best regards
