> The Blueprint configuration processor does not properly handle the case of host group names that include "-" characters (minus sign, dash).
> For example, the following property:
> "ha.zookeeper.quorum": "%HOSTGROUP::os-amb-r6-secha-1427972156-hbaseha-3-6%:2181,%HOSTGROUP::os-amb-r6-secha-1427972156-hbaseha-3-5%:2181,%HOSTGROUP::os-amb-r6-secha-1427972156-hbaseha-3-7%:2181"
> Will cause the Blueprint configuration processor to incorrectly match the host groups (here with "-" characters) to actual assigned host names. During Blueprint processing, this property will be replaced with an incorrect listing of host group names and hosts, which will cause various services to fail at startup. In this particular property, the HDFS services will not be able to connect to the Zookeeper service.
> The Blueprint configuration processor needs to be updated such that host group names can include "-" characters.
> Note: This bug is not affected by the actual DNS host names specified in a cluster creation template. This bug is only affected by the logical host group names having an unexpected character.
> I'm working on a patch for this, and will be submitting it shortly.
