> Project: Kylin
> Issue Type: Improvement
> Components: Job Engine
> Reporter: Shaofeng SHI
> Assignee: Shaofeng SHI
>
> Kylin build dictionary in job engine node, usually this is okay. But if there
> is some high cardinality dimentions, the JVM heap couldn't fit in all
> distinct values, then job engine instance will crash with OOM error.
> Need to enhance on this, move the dictionary building to another process or a
> hadoop node.
