>             Project: Kylin
>          Issue Type: Improvement
>          Components: Job Engine
>    Affects Versions: v1.5.2
>            Reporter: fengYu
>            Assignee: fengYu
>             Fix For: v1.6.0
>         Attachments: 0001-KYLIN-1839-support-kylin-lib-in-HDFS.patch
> in setClasspath, kylin will alway find hive jars from hive dependency using 
> regex, however, this will not change in one process lifetime, so I cache the 
> location of tmpjars and tmpfiles.
> What is more, support extends user lib setting to hdfs path rather than only 
> support local filesystem which will cause upload jars every time if 
> DistributedCache do not exist.
