Subject [jira] [Commented] (FALCON-944) Parallel update APIs create 2 coords
Date Thu, 08 Jan 2015 10:39:34 GMT

    [ https://issues.apache.org/jira/browse/FALCON-944?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14269169#comment-14269169

Suhas Vasu commented on FALCON-944:
-----------------------------------

The approach i have followed - Obtain lock on entity (for which update is issued) and all
its dependent entities before proceeding with update. If obtain locks fail, release all obtained
locks to avoid deadlocks. Once the update is completed, release all corresponding locks.
