@Sam2020 you are missing an important point here that is the Trial installation will always we available for latest software version. Since we have released CM7.4.4 last week so the error you are seeing is expected. You have to change you repo to https://archive.cloudera.com/cm7/7.4.4/redhat7/yum/repodata/ (try accessing this from browser you will understand). Bottom-line is if you have valid subscription you can still have 7.3.1 but if you want trial than you have to go for 7.4.4.

Hi, When I am rejected, I will first check if I have logged into the Oracle website. Then, I will log in to my registered email address. Then search for cloudera, cloudera will automatically log in to the "My Account Home" page. You can try to see if this can help you.

@manu_009, Unfortunately, the CM log kind of shows us more of the same: the server attempts to execute a query but communication with MySQL fails. If this is a problem where the server cannot start, I'd be interested in seeing the logs from startup just to see if there are any clues when CM attempts to connect to MySQL initially. If it gets by that part but then fails later on, that could tell us something. Since the CM log shows it is waiting for packets that never arrive, that means it would be good to look at the network and MySQL to see if it gets connections from CM. I'd recommend the following: - Try starting CM and while CM is starting, run the "show full processlist;" to see if any connections are establishjed You could also use netstat -nap or similar to see if connections are established. - Check MySQL documentation... see if there is a way to debug incoming connections - Try running this on the CM host before trying to start: "tcpdump -i any -w ~/mysql.pcap port 3306" (or whatever port your MySQL is listining on) This will capture all packets going out to and coming back from the MySQL server. After CM does not start, use Ctrl-c to quit tcpdump and finalize the pcap file. You can use WireShark to review communication with MySQL. You could also run tcpdump on the MySQL host (if it is not the CM host) to find out how communication looks on the MySQL host side. Generally, the errors you are seeing do not indicate a problem with CM itself; rather, CM cannot read information from the database.

@hadoopuser2000, Are you still having trouble? The screen shots indicate you need to uninstall before installing again, so I'd try that. I wasn't clear how the screen shots were related to the problem connecting to CM. First, make sure CM is running; # netstat -nap |grep 7180 If you see that it is listening, make sure that you can connect to the host on which Cloudera Manager is installed from whatever client you are using to connect to Cloudera Manager. By public address, the doc means that you should use whatever hostname will resolve to an IP that lets you connect to that host and port.
