Hi there, Whenever instaling Cloudera on Redhat 7 or Centos 7, after disabling the transparent hugepage, the warning still showing, I have already put the following lines to /etc/rc.local, however it is still the same. echo never > /sys/kernel/mm/transparent_hugepage/defrag echo never > /sys/kernel/mm/transparent_hugepage/enabled I tried the following as well. echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled Thank you.

@bgooley Hi Ben, I have done a few trial and error, the initial my.cnf was ok to start the mysql. Once I change the my.cnf to Cloudera recommended settings, it will crash.

Hi there, I have setup a cluster in a private network with internal DNS, how am I able to create external subdomain and point to the servers and access it through internet without any problem? I have created the subdomain but whenever I clicked on the Namenode UI, it will only point to inrternal hostname, not internet hostname. thanks.

Hi there, I am doing an installation and when I use scm_prepare_database.sh using mysql, I got the following error. I checked in the database the ssl is already disabled, any other way to work around? Establishing SSL connection without server's identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification. Thanks
