             Summary: Refactor inconsistent class and variable names
                 Key: TAJO-323
                 URL: https://issues.apache.org/jira/browse/TAJO-323
             Project: Tajo
          Issue Type: Task
            Reporter: Hyunsik Choi
             Fix For: 0.8-incubating


There are inconsistent class and variable names. For example, QueryUnit and task are used in a  mixing way, and QueryUnitAttempt and taskattempt are used in a  mixing way. They reduce readability and make developers confuse.

Now is the right time to correct them. The main object of this issue is to investigate those inconsistent class and variable names and correct them.

However, this work may make many conflicts. In order to minimize the code conflict, we need to make a number of small separate refactors.
