Swapan Shridhar commented on AMBARI-21225: ------------------------------------------ Moved it to 3.0 as I am started the 2.6.1 release process. > 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 > Fix For: 3.0.0 > > 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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
