on: centos7.4 x86_64 using Ambari 2.6.4.0 to install HDP, we configured the UI to build the stack, when we start the build it fails to install and tells us "Server considered task failed and automatically aborted" We see a reference to an HDF repository in these install instructions https://docs.hortonworks.com/HDPDocuments/Ambari/Ambari-2.6.2.0/index.html that is referred to only once. The logfile gives us nothing to pursue: /var/log/ambari-server.log Our local repositories appear okay, Ambari install finds them, yum repolist sees them. we can manually install packages like "accumulo client" a la yum install -y accumulo-something, and this advances us in the GUI to the next install error, so we wonder if there's some naming or reference to our yum Local Repos that Ambari-Server installer can't read; but we sure don't want to enjoy that death by a thousand cuts approach. Will appreciate suggestions how to get past this. Thanks, Justin ... View more
