> Key: AMBARI-8233
> URL: https://issues.apache.org/jira/browse/AMBARI-8233
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 1.7.0
> Reporter: Alejandro Fernandez
> Assignee: Alejandro Fernandez
> Fix For: 1.7.0
>
> Attachments: AMBARI-8233.patch, AMBARI-8233_branch-1.7.0.patch,
> blueprint_error.log, hdp_22_blueprint.json, single_node_cluster.json
>
>
> I created an HDP 2.2 cluster with all of the services except Knox, Kafka, and
> Slider, then exported the blueprint, and removed Ganglia from it.
> Then, I attempted to create a single node cluster using the blueprints and
> ran into a regex error.
> The problem is that one of the properties contains %HOSTGROUP::name% followed
> by another % and the regex match tries to do greedy matching instead of
> minimal.
> For example, storm-site.xml had worker.childopts with
> {code}
> -Xmx768m _JAAS_PLACEHOLDER
> -javaagent:/usr/hdp/current/storm-client/contrib/storm-jmxetric/lib/jmxetric-1.0.4.jar=host=%HOSTGROUP::host_group_1%,port=8650,wireformat31x=true,mode=multicast,config=/usr/hdp/current/storm-client/contrib/storm-jmxetric/conf/jmxetric-conf.xml,process=Worker_%ID%_JVM
> {code}
> While the regex expression in BlueprintConfigurationProcessor.java is,
> {code}
> private static Pattern HOSTGROUP_REGEX =
> Pattern.compile("%HOSTGROUP::(\\S+)%");
> {code}
> Instead, it should be,
> {code}
> private static Pattern HOSTGROUP_REGEX =
> Pattern.compile("%HOSTGROUP::(\\S+?)%");
> {code}
