--------------------------------
Summary: Resource calculator should consider the requested disk
resource at the first stage
Key: TAJO-1696
URL: https://issues.apache.org/jira/browse/TAJO-1696
Project: Tajo
Issue Type: Improvement
Reporter: 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.
