Summary: Support in File-based Tag Retriever to provide tag-deltas
Key: RANGER-4609
URL: https://issues.apache.org/jira/browse/RANGER-4609
Project: Ranger
Issue Type: Improvement
Components: Ranger
Reporter: Abhay Kulkarni
Assignee: Abhay Kulkarni
As a part of test infrastructure, a file-based tag retriever class is created.
When the TagEnricher is configured with this class, a plugin gets the tag from
the configured file.
Please refer to the Service-definition for tag for tagRetrieverClassName in
enricherOptions.
If the value of this option is set to
org.apache.ranger.plugin.contextenricher.RangerFileBasedTagRetriever
then, the tags will be fetched for a file named by the value of the enricher
option
"serviceTagsFileName".
{code:java}
"contextEnrichers":[
{
"itemId": 1,
"name" : "TagEnricher",
"enricher" : "org.apache.ranger.plugin.contextenricher.RangerTagEnricher",
"enricherOptions" : {
"tagRetrieverClassName":
"org.apache.ranger.plugin.contextenricher.RangerAdminTagRetriever",
"tagRefresherPollingInterval": 60000
}
}]{code}
This enhancement supports specifying another enricher option "tagFileCount".
When this is set to a value greater than 0, each successive call made to fetch
tags will provide tags from the file name obtained by adding a suffix [0..
tagFileCount-1].json to the file named by the option "serviceTagsFileName".
When tag-delta files are set up with appropriate suffixes, this simulates the
fetching of successive tag-deltas for processing.
