Description

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:

2016-04-04 15:21:05,809 ERROR org.apache.tajo.catalog.CatalogServer:
