-----------------------------------

             Summary: Build cube on step 'build Dimension Dictionary ', the contents of non-dimensional
columns are also checked and built
                 Key: KYLIN-3924
                 URL: https://issues.apache.org/jira/browse/KYLIN-3924
             Project: Kylin
          Issue Type: Bug
          Components: Job Engine, Tools, Build and Test
    Affects Versions: v2.6.1
            Reporter: wangxiaojing
         Attachments: builderr.log

Version 2.6.1 ,checks the content size of each field in the table while building Dimension
Dictionary, and build all fields in the table with a dictionary.

Suggestion:
1. Large content fields may not be dimension columns, in fact, it is not necessary to check
the value size of non-dimension columns´╝îonly check dimension columns.

2. If the value of some fields in the dimension table is too long, the exception is not clear,
can not be located the problem column quickly.

3. There is no need to build dictionaries for non-dimensional columns
