I am fed of of this error coming on random nodes during HDP2.2 install using Ambari. Not sure what this means. All the nodes are similarly configured. Each time I do a fresh install, a random node will fail with the same error.
Fail: Execution of '/usr/bin/yum -d 0 -e 0 -y install hadoop_2_2_*-yarn' returned 1. Package jdk-1.7.0_45-fcs.x86_64.rpm is not signed
