Subject [jira] [Commented] (ZOOKEEPER-1364) Add orthogonal fault injection mechanism/framework
Date Wed, 14 Dec 2016 16:59:58 GMT

ASF GitHub Bot commented on ZOOKEEPER-1364:

Github user eribeiro commented on the issue:

    @yufeldman Sure, totally agree about this being a separate issue! :+1: 
    My only concern is that **IF** we decide to introduce this injection framework into ZK
**after merging ZOOKEEPER-2549** then some of the mocking and reflection changes introduced
by ZOOKEEPER-2549 for the purposes of testing become redundant, so basically we would have
to undo parts of it (but not the bug fix, of course). See this PR for a concrete idea of what
I am trying to say.
    But you raised a very important point: **ZOOKEEPER-2549 is critical, and delaying its
merging is gonna be bad for the project release, IMHO.** So, I am all for you keep going your
work (congrats, btw) and run this as a future issue. Or whatever the committers find more
suitable.  /cc @fpj @rgs1 @hanm @phunt

> Hadoop has a mechanism for doing fault injection (HDFS-435). I think it would be useful
if something similar would be available for ZooKeeper.
