> Key: TAJO-1206
> URL: https://issues.apache.org/jira/browse/TAJO-1206
> Project: Tajo
> Issue Type: New Feature
> Reporter: Hyoungjun Kim
> Assignee: Hyoungjun Kim
> Attachments: Tajo-ThriftServer.png
>
>
> Currently Tajo supports only Java client. To support multiple languages like
> Python, Thrift is very useful tool. Hive also supports multiple languages
> using Thrift server.
> Thrift Server may be useful to separate a user from Tajo cluster for security
> issues.
> In this issue, The following functions will be implemented.
> - Thrift server for Tajo
> - Web UI for monitoring Thrift server
> - CLI for Thrift server
