Description

KYLIN-883 introduces "kylin.job.hive.database.for.intermediatetable" so that user can specify a database where kylin's intermediate tables are stored. However the feature is broken and cause cube creation to fail at "Extract Fact Table Distinct Columns" step.

The reason is in CubingJobBuilder.java, we didn't pass the configured database name into createFactDistinctColumnsStep.

addCubingSteps(CubeSegment seg, String cuboidRootPath, CubingJob result) {
        // ...code ommitted...
        final CubeJoinedFlatTableDesc intermediateTableDesc = new CubeJoinedFlatTableDesc(seg.getCubeDesc(), seg);
        
        // SHOULE BE dbname.tblname, BUT WAS tblname
        final String intermediateHiveTableName = getIntermediateHiveTableName(intermediateTableDesc, jobId);
        
        // ...code ommitted...
        result.addTask(createFactDistinctColumnsStep(seg, intermediateHiveTableName, jobId));
