-------------------------------------
Fix Version/s: 3.1.0
(was: 3.0.0)
> Support for macro based property definitions in Ambari Views
> ------------------------------------------------------------
>
> Key: AMBARI-21225
> URL: https://issues.apache.org/jira/browse/AMBARI-21225
> Project: Ambari
> Issue Type: Improvement
> Components: ambari-views
> Affects Versions: 2.4.0
> Reporter: Sridhar Sailappan
> Priority: Major
> Fix For: 3.1.0
>
> Attachments: Patch_AmbariViewUtils_Macro.txt
>
>
> The attached patch for Ambari Views provides support for property
> configurations with macro based definitions (relying on variable expansion of
> Hadoop Configuration).
> e.g., Consider the following definition of properties for HDFS.
> 1) In Advanced core-site, property "fs.defaultFS" is defined to have value
> "${fs.defaultFS.dev}"
> 2) In Custom core-site, property "fs.defaultFS.dev" is defined to have value
> "hdfs://dev-sandbox.hortonworks.com:8020"
> Now, when referencing the property "fs.defaultFS", the value should be
> resolved to "hdfs://dev-sandbox.hortonworks.com:8020".
> This is typical variable expansion that is expected in Hadoop Configuration.
> Refer:
> https://hadoop.apache.org/docs/r2.6.0/api/org/apache/hadoop/conf/Configuration.html
> This functionality of variable expansion is not available with Ambari Views.
> The attached patch (on branch-2.4.0) addresses this need.
