>                 URL: https://issues.apache.org/jira/browse/TAJO-1696
>             Project: Tajo
>          Issue Type: Improvement
>          Components: Resource Manager
>            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.
