Summary: Build dictionary out of job engine
Key: KYLIN-1178
URL: https://issues.apache.org/jira/browse/KYLIN-1178
Project: Kylin
Issue Type: Improvement
Components: Job Engine
Reporter: Shaofeng SHI
Assignee: ZhouQianhao
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.
