> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.1.0
> Reporter: Robert Levas
> Assignee: Robert Levas
> Priority: Critical

> The webhcat-site/templeton.hive.properties property value substitution should
> be done by ambari-server. This value is more complicated than others since
> the (embedded) hive.metastore.uris property is a list of thrift URIs
> generated using the set of hosts the Hive Metastore is installed on. This
> list of hosts comes from the clusterHostInfo/hive_metastore_host value, which
> in the KerberosHelper (org.apache.ambari.server.controller.KerberosHelper) is
> available as a comma-delimited list of hosts.
> {code}
> clusterHostInfo/hive_metastore_host = "host1,host2,host3"
> {code}
> To generate configuration values when enabling Kerberos, the KerberosHelper
> class uses
> org.apache.ambari.server.state.kerberos.AbstractKerberosDescriptor#replaceVariables
> to replace variables specified in the Kerberos Descriptor. Currently this
> mechanism uses a simple replacement scheme, which is not sufficient to
> generate string using a delimited list of values.
> In order to solve this issue, "functions" need to be applied to replacement
> data before making the substitution. In this case a "function" named "each"
> will be created that takes the following arguments:
> * pattern with placeholders
> * delimiter to use to concatenate values generated using the patter
> * regex to use to split the original string
> For example:
> {code:title=function declaration, commas are escaped when not intended to
> separate function args}
> each(thrift://%s:9083, \\,, \s*\,\s*)
> {code}
> To indicate this function is to be used, the following Kerberos Descriptor
> variable replacement syntax is to be used:
> {code}
> ${clusterHostInfo/hive_metastore_host|each(thrift://%s:9083, \\,, \s*\,\s*)}
> {code}
> Note: \ characters need to be escaped in JSON structure values. For example:
> {code}
> "some.property" :
> "${clusterHostInfo/hive_metastore_host|each(thrift://%s:9083, \\\\,,
> \\s*\\,\\s*)}"
> {code}
> If clusterHostInfo/hive_metastore_host = "host1,host2,host3", the result
> would be
> {code}
> thrift://host1:9083\,thrift://host2:9083\,thrift://host3:9083
> {code}
