             Summary: Report error when a dimension using "dict" encoding and also configured Global dictionary for "distinct_count" measure
                 Key: KYLIN-2679
                 URL: https://issues.apache.org/jira/browse/KYLIN-2679
             Project: Kylin
          Issue Type: Bug
          Components: Metadata, Query Engine
            Reporter: Shaofeng SHI


This is a problem reported by community user Sonny Heer:

After finally getting the global dictionary to work with building the cube there are now exceptions during query.  

ERROR in query: "AppendTrieDictionary can't retrive value from id"

The cube has a UHC dimension, which also appeared in a count distinct measure. Then a global dictionary is created for it, but Global dictionary doesn't support decoding, then there is such an error during query time. While this wasn't even checked when the cube is created.
