             Summary: Knox: Reorder of query parameters breaks Ambari logic for retrieving configs
                 Key: AMBARI-24989
                 URL: https://issues.apache.org/jira/browse/AMBARI-24989
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.7.3
            Reporter: Andrii Tkach
            Assignee: Andrii Tkach
             Fix For: 2.8.0


Knox proxy sometimes modifies service config version request during transferring.
I extended logging on the ambari server to track actual requests. 
Direct API request:
{noformat}
https://172.27.16.232:8443/api/v1/clusters/cl1/configurations/service_config_versions?
service_name=HBASE&service_config_version.in(12)%7C
service_name.in(ATLAS,YARN,RANGER,HIVE,HDFS,MAPREDUCE2,SPARK2,TEZ,DRUID,ZOOKEEPER,AMBARI_METRICS,KAFKA,RANGER_KMS)&is_current=true&_=1542046206583
{noformat}
Via Knox:
{noformat}
https://ctr-e138-1518143905142-579999-01-000002.hwx.site/api/v1/clusters/cl1/configurations/service_config_versions?
service_name=HBASE&is_current=true&service_config_version.in(12)%7C
service_name.in(ATLAS,YARN,RANGER,HIVE,HDFS,MAPREDUCE2,SPARK2,TEZ,DRUID,ZOOKEEPER,AMBARI_METRICS,KAFKA,RANGER_KMS)&_=1542046206583
{noformat}

In both cases same request was used on client side:
{noformat}
/api/v1/clusters/cl1/configurations/service_config_versions?
service_name=HBASE&service_config_version.in(12)|
service_name.in(ATLAS,YARN,RANGER,HIVE,HDFS,MAPREDUCE2,SPARK2,TEZ,DRUID,ZOOKEEPER,AMBARI_METRICS,KAFKA,RANGER_KMS)&is_current=true&_=1542046206583
{noformat}

As we can see Knox proxy reordered request parameters (is_current=true was moved) and completely changed request logic.
