    I mean, this issue is not addressing the fundamental problem. I believe 
that we need to devise a better way to map Tajo columns and HBase columns.

> There is no limit on number of column families in HBase, in theory. Actually, 
> many users of HBase create  from several dozen of column families to a single 
> HBase table. But when create external table to Tajo with HBase and 120 column 
> families, the DDL failed as following:
> {code:xml}
