Sailesh Patel commented on HBASE-22846:
---------------------------------------
Per my investigation, The error is from :
247 private Response createOrUpdate(final NamespacesInstanceModel model, final
UriInfo uriInfo,
248 final Admin admin, final boolean updateExisting) {
249 NamespaceDescriptor.Builder builder = NamespaceDescriptor.create(namespace);
250 builder.addConfiguration(model.getProperties());
<================================= Model is Null
This is called first from:
public Response post(final NamespacesInstanceModel model, <================
Null here
177 final @Context UriInfo uriInfo) {
servlet.getMetrics().incrementRequests(1);
183 return processUpdate(model, false, uriInfo); <========================Model
is null here also
184 }
Comparing with :
public Response postNoBody
try{
200 NamespacesInstanceModel model = new NamespacesInstanceModel(namespace);
<=====I do not see this on the above post method.
201 return processUpdate(model, false, uriInfo);
> Internal Error 500 when Using HBASE REST API to Create Namespace.
