wangxiaojing updated KYLIN-4368:
--------------------------------
Description:
At present, global dictionary can reuse other columns in the same cube, but
cannot reuse the dictionaries of other cubes in the cluster.
It is suggested that not only the global dictionaries of the same cube can
be reused, but also the global dictionaries of other cubes can be reused, which
can greatly reduce the build time of dictionaries and avoid the repeated build
of dictionaries.
I add this feature called "Global domain dictionary" for tire-tree global
dictionary implementation, issue KYLIN-4335
This issue is Global domain dictionary for Mr/Hive implementation.
