---------------------------------
Summary: Ranger policy list doesn't support sorting by field
Key: RANGER-3500
URL: https://issues.apache.org/jira/browse/RANGER-3500
Project: Ranger
Issue Type: Bug
Components: admin
Affects Versions: 2.1.0
Reporter: Xuze Yang
When getting the ranger policy list, we may want to sort the returned policy
list according to certain fields, such as policyId, policyName and etc. But
case shows that adding the parameters sortBy and sortType to the url has no
effect (eg: http://192.168.0.12:6080/service/plugins/
policies/service/2?sortBy=policyName&sortType=desc&serviceName=default-Hdfs). I
look through the source code and find that code supports sorting by fields, but
due to some code bugs, it did not really take effect.
The main reason for the problem is that when the SearchFilter is copied deeply,
only the params is copied, the sortBy and sortType attributes is omitted. The
code show as follows:
{code:java}
Map<String, String> paramsCopy = new HashMap<>(filter.getParams());
SearchFilter searchFilter = new SearchFilter(paramsCopy);
{code}
