----------------------------------
Summary: StorageCleanupJob may delete cube id data of new built
segment because of cube cache in CubeManager
Key: KYLIN-3994
URL: https://issues.apache.org/jira/browse/KYLIN-3994
Project: Kylin
Issue Type: Bug
Affects Versions: v2.5.2
Reporter: Liu Shaohui
In our production cluster, we found that the cube id data of a new-built
segment is deleted by the StorageCleanupJob.
After checking the code of cleanUnusedHdfsFiles in StorageCleanupJob, we found
that there is a bug here: CubeManager read all cube meta in initiation and
cache it for later
listAllCubes operations, the metadata will be out of data after listing the
hdfs working dir.
So the working directory of a finished job may be deleted unexpectedly.
