ASF GitHub Bot commented on KYLIN-3617:
---------------------------------------
hit-lacus opened a new pull request #376: KYLIN-3617 Add javadoc for magic
number in isTaskExecutableOutput
URL: https://github.com/apache/kylin/pull/376
The method `isTaskExecutableOutput` is quite confusing to me, so I add my
understanding as javadoc to that method, and I guess it might be helpful to
other developers.
