Conda Install Package option throws unknown error

[Shouvanik Haldar]

Hi,

I am out of ideas now. Perhaps you can help.

We have AWS EMR cluster, and Anaconda 2.3.0 has been installed on master node (Linux).

First package gets installed via conda install.

But when I try to install another package, we get the error.

Any idea?

Appreciate your help!
