Big Data for System Admins

Hello,
I have been working as Solaris/Linux Admin since past 8 years. I am looking options for my profile change, but there is some limitation. I worked as 24x7 support for admin, server support, high availability, etc. But been worked on developing side and scripting part.
When I search for Big Data jobs on internet, most of them deal with java, scripts and development part. I just want to know, is there any scope for hardcore system admin in Big Data, which deals with admin parts only ? Like managing Namenode, datanode, performance and other tasks in day to day routine, as we do as Unix admin. I have been reading Big data books for sometime and there are many tasks which are related to admin parts, but not sure if that kind of job exists in market.
Thanks in advance.

NAME
myproxy-admin-change-pass - change credential passphrase SYNOPSIS
myproxy-admin-change-pass [ options ] DESCRIPTION
The myproxy-admin-change-pass command changes the passphrase used to encrypt a credential in the MyProxy repository. The command first prompts for the current passphrase for the credential, then prompts twice for the new passphrase. If an empty passphrase is given, the credential will not be encrypted. It accesses the repository directly and must be run on the machine where the myproxy-server(8) is installed from the account that owns the repository. OPTIONS
-h Displays command usage text and exits. -u Displays command usage text and exits. -s dir Specifies the location of the credential storage directory. The directory must be accessible only by the user running the myproxy- server process for security reasons. Default: /var/lib/myproxy or /var/myproxy or $GLOBUS_LOCATION/var/myproxy -l username Specifies the MyProxy account under which the credential should be stored. -k name Specifies the credential name. -S, --stdin_pass By default, the command prompts for a passphrase and reads the passphrase from the active tty. When running the command non-inter- actively, there may be no associated tty. Specifying this option tells the command to read passphrases from standard input without prompts or confirmation. EXIT STATUS
0 on success, >0 on error AUTHORS
See http://myproxy.ncsa.uiuc.edu/about for the list of MyProxy authors. SEE ALSO
