      Description

      Problem:

      HBase rest server returns a 503 Server Unavailable when generating a scanner object fails using the hbase rest server interface.

      The error code returned by hbase rest server is incorrect and may mislead the user.

      The exception caused by the wrong filter should ideally give Response.Status.BAD_REQUEST but it gives Response.Status.SERVICE_UNAVAILABLE which may mislead the user.

      Root cause:

      The ScannerModel.buildFilter throws JsonParseException/JsonMappingException depending on the below described scenarios which is not handled by the ScannerResource.update() method and thus returns Response.Status.SERVICE_UNAVAILABLE as response

        public static Filter buildFilter(String s) throws Exception {
          FilterModel model = getJasonProvider().locateMapper(FilterModel.class,
              MediaType.APPLICATION_JSON_TYPE).readValue(s, FilterModel.class);
          return model.build();
        }
      

       

      Steps to reproduce :

      (Scenario 1) JsonMappingException

      • Run the following having a wrong tag type1:
        curl -vi -X PUT -H "Content-Type:text/xml" -d '<Scanner batch="100"><filter>{"type1": "PrefixFilter","value": "cg=="}</filter></Scanner>' "http://localhost:11120/test/scanner/"
        
      • Response
        * Trying 127.0.0.1...
        * Connected to localhost (127.0.0.1) port 11120 (#0)
        > POST /test/scanner/ HTTP/1.1
        > Host: localhost:11120
        > User-Agent: curl/7.47.0
        > Accept: */*
        > Content-Type: text/xml
        > Content-Length: 89
        > 
        * upload completely sent off: 89 out of 89 bytes
        < HTTP/1.1 503 Service Unavailable
        < Content-Type: text/plain
        < Content-Length: 13
        < 
        Unavailable
        * Connection #0 to host localhost left intact
