vrozov edited a comment on issue #1333: DRILL-6410: Memory leak in Parquet Reader during cancellation URL: https://github.com/apache/drill/pull/1333#issuecomment-401862300 @ilooner I guess by "last discussion" you refer to the discussion between you, me and @sachouche, where "majority" does not mean the community majority. In the Apache, any contributor can provide a solution that (s)he considers to be the best solution possible and then it can either be accepted by the community/contributor or blocked with -1 (requires technical justification). If another contributor provides an alternative solution, a community may decide to go with the alternate solution as long as it addresses technical concerns of the initial contribution. For this particular case, my requirements are a) a unified approach (@parthchandra has the same requirement) and b) the ability to cancel tasks asynchronously. If that can be done with the approach outlined in PR #1257 and a contributor will change it to address all the issues, let's move forward with the alternate approach. A note regarding the complexity of the implementation. This implementation uses public java concurrency classes as well. It does not rely on unsupported or unsafe to use Java classes and/or API. Basically, `LockSupport` is the same first-class concurrency construct as `Thread` or `CountDownLatch` classes. The primary use case for using those constructs is to create a combination of `ExecutorService` and a `CountDownLatch` that is not provided by the Java itself. To summarize, I am perfectly fine to go with an alternate solution or with another committer to review the PR, it will be against Apache way to force a committer to review or commit a change, that (s)he is not comfortable with.
