Subject Re: MR AppMaster unable to load native libs
Date Wed, 13 Aug 2014 07:47:37 GMT
hi Susheel,

Thanks for your input. I did build the libs for 64 bit but, still the problem was there.
Though the problem is resolved now.
I had to configure the property: yarn.app.mapreduce.am.env

Cheers,
Subroto Sanyal
