-----------------------------------------
Summary: Blueprint not properly handling host group names that
include "-" characters
Key: AMBARI-10388
URL: https://issues.apache.org/jira/browse/AMBARI-10388
Project: Ambari
Issue Type: Bug
Components: ambari-server
Affects Versions: 2.1.0
Reporter: Robert Nettleton
Assignee: Robert Nettleton
Priority: Critical
Fix For: 2.1.0
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.
