ChangjiGuo commented on pull request #1168: KYLIN-4433 use cube config when uhc 
step enabled
URL: https://github.com/apache/kylin/pull/1168
 
 
   issue: https://issues.apache.org/jira/browse/KYLIN-4433
       If the system level configuration is used, it will cause the dictionary 
to be built repeatedly, so I think the configuration of the cube should be used 
here.
       Thanks!

> Hi guys :
>     In the _Configuration overrides_ step of _Cube Designer_, I added the 
> following configuration:
> {code:java}
> kylin.engine.mr.build-uhc-dict-in-additional-step = true
> {code}
>     When building the cube, it will take an extra step to handle the UHC 
> dimensions, but I found that in the step of 'Build Dimension Dictionary', it 
> still builds the dictionary that has been built in the previous step which 
> takes double the time to build the dictionary.
>     When I traced the source code, I found that our expected code was not 
> executed due to _config.isBuildUHCDictWithMREnabled() == false_ :
> {code:java}
> if (config.isBuildUHCDictWithMREnabled() && uhcColumns.contains(col)) {
>     colDir = new Path(dictPath, col.getIdentity());
> } else {
>     colDir = new Path(factColumnsInputPath, col.getIdentity());
> }
> {code}
>     The root cause is that the configuration used in this step is the 
> environment configuration, but our parameters are set in the cube:
> {code:java}
> final KylinConfig config = KylinConfig.getInstanceFromEnv();{code}
>     I think the configuration of the cube should be used here instead of the 
> environment configuration.
