Update Name: Interim Fix 478190

Fix ID: sym-7.1.2-build478190-citizens

Publication Date: December 29, 2017

When IBM Spectrum Symphony 7.1.2 is installed on Apache Ambari for use with IBM Open Platform Hadoop distributions, the Resource Manager and Node Manager cannot be started after the Hadoop 2.7.2-20 patch is applied. This issue occurs because Hadoop 2.7.2-20 is not a supported version for IBM Spectrum Symphony. This interim fix enhances IBM Spectrum Symphony to support patch-level upgrade for Hadoop 2.7.2.
