@HanzalaShaikh This seems a very old cosmetic issue in CM. What version you are using?    It appears in older versions we had some early bugs caused by the addition of a new jar file in the classpath directory (/usr/share/cmf/schema/../lib/* ) used by the scm_prepare_db.sh script. This new jar contained a log4j.properties file that was not configured to use the log4j appender A, and overwrote the original properties from the proper log4j.properties file in the original jar file. ...

Log in to CM database server. Check if there is more than one user admin in the system. Take a back up of password_hash and password_salt of the Admin user and paste them into a text editor: SELECT password_hash, password_salt FROM users WHERE user_id = 1; Update password_hash and password_salt for user "admin" using the following command: update USERS set password_hash='2518db3278f704558ece63f469af87a7c12dbad8ff0971d3b677e291d61b44fc', password_salt=-5792243850706636683 WHERE user_id = 1;  Log in to the CM interface using admin user and admin password.   ...

@mike_bronson7 I meant to say there is not a bunch of people using package install because of following reason[1]: Cloudera does not support clusters that are not deployed and managed by Cloudera Manager. If you choose to install CDH manually using these instructions, you cannot use Cloudera Manager to install additional parcels. This can prevent you from using services that are only available via parcel. For testing purpose you are free to choose any method but it depends what you are looking i.e easy managing of cluster using CM web UI or just want to play with a demo installation.  Regarding the end of life question, Yes that's the nature of software support that end of the day it will be end of life after some years. For Cloudera software support cycle you can here is a glance:  https://www.cloudera.com/legal/policies/support-lifecycle-policy.html   Cheers!   [1] https://docs.cloudera.com/documentation/enterprise/5-16-x/topics/install_cloudera_packages.html ...
