General Requirements

Trafodion requires an x86 version of Linux.

The current release of Trafodion has been tested with:

• 64-bit Red Hat Enterprise Linux (RHEL) or CentOS 6.5 - 6.8

• Cloudera CDH 5.4 - 5.7

• Hortonworks HDP 2.3 - 2.4

• Java 1.7

• gcc compiler 4.4

Other OS releases may work, too. The Trafodion project is currently working on better support for more distribution and non-distribution versions of Hadoop.
