What is the use of Impala Catalog server web server username and Catalog server web server user password.
I see the fields are admin and ******
1) Are these default values? what is the default password for this?
2)On google, I could not find a description for this parameter. Is there any place I can find a detailed description for each parameter that I see in Cloudera manager?
The main purpose of the web page is to show catalog version,os details , hardware info,process info.
you can also see the JVM memory total usage , rpc details in terms of time between state ,catalog and demons.
varz is self explainatory .
you wouldnt need username / password if you are having the credentials of Cloudera manager with full administrative rights.
