Below is the minimum OS requirements mentioned in the document.
Red Hat Enterprise Linux (RHEL) v5.x or 6.x (64-bit)
CentOS v5.x or 6.x (64-bit)
SUSE Linux Enterprise Server (SLES) 11, SP1 (64-bit)
might be very basic questions but any one has idea does HDP installs and works on CentOS 32 bit versions
