@Lokesh Mukku

Can you rename the /etc/passwd.lock file and attempt the installation again?


Thanks a lot

@amarnath reddy pappuI search *.lock files in /etc but did not find any file with name of .lock. Please help me

@Lokesh Mukku are you checking this in host where "Yarn+Mapreduce" is being installed?
