[jira] [Commented] (IGNITE-3361) Service is not redeployed after a node is left topology

["Semen Boikov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-3361?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15350946#comment-15350946 ] 

Semen Boikov commented on IGNITE-3361:
--------------------------------------

Looks like this is incorrect condition in GridServiceProcessor:reassign
{noformat}
if (!used.contains(e.getKey())) {
    if (e.getValue() < maxPerNodeCnt) {
        e.setValue(e.getValue() + 1);

        if (--remainder == 0)
            break;
    }
}
{noformat}

With the attached test maxPerNodeCnt=0 which means unlimited, but check 'if (e.getValue() < maxPerNodeCnt)' fails and service is not redeployed.
