> *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
> {code:java}
> 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();
> }
> {code}
>
> *Steps to reproduce :*
> (Scenario 1) *JsonMappingException*
> * Run the following having a *wrong tag* {{type1}}:
> {code:java}
> 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/";
> {code}
> * {{Response}}
> {noformat}
> * Trying 127.0.0.1...
> * Connected to localhost (127.0.0.1) port 11120 (#0)
> > POST /test/scanner/ HTTP/1.1
