Key: YARN-3114 URL: https://issues.apache.org/jira/browse/YARN-3114 Project: Hadoop YARN Issue Type: Bug Components: resourcemanager Reporter: zhihai xu Assignee: zhihai xu Priority: Minor
It would be better to consider integer(long) overflow when compare the time in DelegationTokenRenewer. When compare time in DelegationTokenRenewer#DelayedTokenRemovalRunnable to cancel token , it will have problem when currentTimeMillis is close to Long.MAX_VALUE. The safer way to compare time will compare the time difference: change {code} if (e.getValue() < System.currentTimeMillis()) { {code} to {code} if (e.getValue() - System.currentTimeMillis() < 0) { {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
