[jira] [Commented] (HELIX-518) Add integration tests to ensure helix tasks work as expected during master failover

["Zhen Zhang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HELIX-518?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14155599#comment-14155599 ] 

Zhen Zhang commented on HELIX-518:
----------------------------------

[~kanak] can we call TaskRunner#cancel or Task#cancel directly? I see it can be called either during state transition or timeout. If we call it directly, then the task will be left in RUNNING state?
