> ---------------------------------------------------------
>
> Key: TAJO-1221
> URL: https://issues.apache.org/jira/browse/TAJO-1221
> Project: Tajo
> Issue Type: Improvement
> Components: tajo master
> Reporter: Hyunsik Choi
> Assignee: Jaehwa Jung
> Labels: failure-handling, fault-tolerance, high-availability
> Fix For: 0.9.1
>
>
> *Problem*
> We TajoClient is opened, TajoClient initially tries to connect TajoMaster.
> This manner does not guarantee high availability. A known TajoMaster host may
> be not work anymore. So, this manner still has some failure point.
> Also, this manner prohibits a Tajo cluster to run on some dynamic cluster
> environments like Yarn.
> *Solution*
> Tajo HA client should get directly TajoMaster addresses and others from HA
> component without contacting TajoMaster.
