Re: Error while adding YRAN+MAPREDUCE

Hi @Lokesh Mukku

Relevant piece I think, from your output, is that it's failing on adding the yarn-ats user because there is a lock on the passwd file;

Execution of 'useradd -m -G hadoop -g hadoop yarn-ats' returned 1. useradd: existing lock file /etc/passwd.lock without a PID useradd: cannot lock /etc/passwd; try again later.

You need to find out what currently has a lock on your passwd file. Ex sudo lsof /etc/passwd...
