Subject [helix] 13/14: Fix node swap test.
Date Wed, 22 May 2019 23:41:38 GMT
This is an automated email from the ASF dual-hosted git repository.

hulee pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/helix.git

commit 7f4044ffedc8a57ee4c635daf747352f1fcddc37
Author: Jiajun Wang <jjwang@linkedin.com>
AuthorDate: Tue Nov 13 16:59:18 2018 -0800

    Fix node swap test.
    
    Add sleep to stablize the test. Several cluster operations require controller reaction
before checking.
