-----------------------------
Resolution: Fixed
> Resource calculator should consider the requested disk resource at the first

> Key: TAJO-1696
> URL: https://issues.apache.org/jira/browse/TAJO-1696
> Project: Tajo
> Issue Type: Improvement
> Reporter: Jihoon Son
> Assignee: Jihoon Son
> Fix For: 0.11.0
>
>
> Resource calculator currently considers only cpu and memory. However, disk is
> an important resource in the first stage, so should be considered for
> available resource calculation.
> In addition, in the current implementation, a worker sends a heartbeat
> whenever it finishes processing half of the assigned tasks. So, the problem
> of ignoring disk resource makes the first heartbeat delayed during the first
> stage, thereby making the query execution slow.
