---------------------------------

             Summary: Change the size of the VALUE_ column in OPTIONS table
                 Key: TAJO-2115
                 URL: https://issues.apache.org/jira/browse/TAJO-2115
             Project: Tajo
          Issue Type: Improvement
          Components: Catalog
            Reporter: Jaehwa Jung
            Assignee: Jaehwa Jung
             Fix For: 0.12.0


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

{code}

Above error made by the column size of OPTIONS table on catalog. We need to update its size.
