Getting "Existing lock /var/run/yum.pid: another copy is running as pid ..." during bootstraping in EMR

I need to install python3 in my EMR cluster (AMI 3.1.1) as a part of bootstraping step. So I added the following command:

sudo yum install -y python3

But everytime I got an error saying the following:

Existing lock /var/run/yum.pid: another copy is running as pid 1829.
Another app is currently holding the yum lock; waiting for it to exit...
The other application is: yum

How can I avoid this error? Or is there a way to install Python 3 without going through this route?

Solution

  • I ended up installing from the source code:

    wget --no-check-certificate -O Python-3.4.2.tgz "https://www.python.org/ftp/python/3.4.2/Python-3.4.2.tgz"
tar xvfz Python-3.4.2.tgz
cd Python-3.4.2
./configure
make
sudo make altinstall
