Description

Classes used in Ranger REST API must be annotated to ignore unknown attributes that might be found in the response from the server - with @JsonIgnoreProperties(ignoreUnknown=true). If not, the older version of REST clients might fail to process the response from newer version of Ranger Admin - like HDP-2.3.* plugins fail while reading the policies downloaded from Erie TP version of Ranger Admin.
To avoid this issue, ensure that all classes, including the inner classes, are annotated with @JsonIgnoreProperties(ignoreUnknown=true). Following inner classes currently miss this annotation:
RangerServiceDef.RangerEnumDef
RangerServiceDef.RangerEnumElementDef
RangerServiceDef.RangerServiceConfigDef
RangerServiceDef.RangerResourceDef
RangerServiceDef.RangerAccessTypeDef
RangerServiceDef.RangerPolicyConditionDef
RangerServiceDef.RangerContextEnricherDef
RangerPolicy.RangerPolicyResource
RangerPolicy.RangerPolicyItem
RangerPolicy.RangerPolicyItemAccess
RangerPolicy.RangerPolicyItemCondition
