[ https://issues.apache.org/jira/browse/KYLIN-5416?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17683733#comment-17683733 ]
longfeiJiang commented on KYLIN-5416:
-------------------------------------
*Design*
Before building the dictionary column lock, check whether the current spark application has been successfully registered to the worker,
if not, wait until the worker is registered and then lock the dictionary column.

> model_64 has obtained the lock of the global dictionary, but model_64 has not been built because model_30 has obtained all the resources, and the model_30 building job has not obtained the lock, and all resources are still unable to be build, forming a deadlock.
