Mobin Ranjbar created HADOOP-13295: -------------------------------------- Summary: Possible Vulnerability in DataNodes via SSH Key: HADOOP-13295 URL: https://issues.apache.org/jira/browse/HADOOP-13295 Project: Hadoop Common Issue Type: Bug Reporter: Mobin Ranjbar
I suspected something weird in my Hadoop cluster. When I run datanodes, after a while my servers(except namenode) will be down for SSH Max Attempts. When I checked the 'systemctl status ssh', I figured out there are some invalid username/password attempts via SSH and the SSH daemon blocked all incoming connections and I got connection refused. I have no problem when my datanodes are not running. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
