> Key: KYLIN-3312
> URL: https://issues.apache.org/jira/browse/KYLIN-3312
> Project: Kylin
> Issue Type: Bug
> Components: Job Engine
> Affects Versions: v2.0.0
> Reporter: RenZhiMin
> Priority: Major
>
> In the cube design, the COUNT_DISTINCT indicator USES the global dictionary.
> When building a cube, a dictionary file is generated at HDFS, and the
> corresponding directory is:
> "/ resources/GlobalDict/dict/database. The tableName/column/", at the same
> time will generate metadata information in hbase metadata, metadata in the
> hbase rowkey information:"/dict/database. The tableName/column/". The value
> information specifies the corresponding HDFS path.
> The problem is that the corresponding HDFS data and hbase data are not
> deleted when the cube is deleted. Another HDFS data path and hbase metadata
> rowkey information did not specify the concrete cube, if a table column in
> more than one cube is to use global dictionary, can lead to multiple share a
> dictionary data cube
