             Summary:  Speedup LookupStringTable, use HashMap instead of 
ConcurrentHashMap
                 Key: KYLIN-2527
                 URL: https://issues.apache.org/jira/browse/KYLIN-2527
             Project: Kylin
          Issue Type: Improvement
            Reporter: hongbin ma
            Assignee: hongbin ma


concurrent hash map here is a overkill, it should be faster to init a normal 
hash map. the next step might be to cache the lookupStringTable
