[jira] [Comment Edited] (YARN-10316) FS-CS converter: convert
maxAppsDefault, maxRunningApps settings
[ https://issues.apache.org/jira/browse/YARN-10316?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17142182#comment-17142182 ]

I'm not sure if negative numbers are treated as errors. I haven't seen any preconditions & errors checks in FS either, so it's likely that all comparisons will be performed against the negative value (which doesn't really cause any harm during runtime).
