[jira] [Closed] (STORM-3195) IllegalArgumentException when rolling
upgrade nimbus from 1.x to 2.x
[ https://issues.apache.org/jira/browse/STORM-3195?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ethan Li closed STORM-3195.
---------------------------
Resolution: Invalid
Community 1.x will not have this issue because https://github.com/apache/storm/pull/2325 wasn't merged into 1.x. The worker count will always be int and acker executer number will always be int.
Our internal version 1.x has https://github.com/apache/storm/pull/2325 feature. And that's why it happened.

> We were rolling upgrading our storm cluster to 2.x and we found this error from nimbus.log. It's not necessary to do rolling upgrade but good news is we basically made it work.
