Hi,

Ambari agent uses default package manager to install packages for
components (yum for RedHat, CentOS and zypper for SLES). yum or zypper
can't be run in parallel in a single node, they create locks once they
started. But you will have hadoop components installing in parallel on
different nodes.

BR,
Dmytro Sen
