Jaehwa Jung created TAJO-2115:
---------------------------------
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}

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