Description

Hi,

we are about to upgrade our cluster from 0.9.1-incubating to 0.10.0. I'm currently testing whether the functionality is still working with 0.10.0 in VMs.

On 0.10.0 the following throws the exception mentioned below:
...
NimbusClient nimbusClient = NimbusClient.getConfiguredClient(readConfig);
Client client = nimbusClient.getClient();
ClusterSummary clusterInfo = client.getClusterInfo();

Exception:
org.apache.thrift7.protocol.TProtocolException: Required field 'nimbus_uptime_secs' is unset! Struct:ClusterSummary(supervisors:[SupervisorSummary(host:n3.t3k.siemens.com, uptime_secs:24297, num_workers:4, num_used_workers:0, supervisor_id:4a87f03b-ea91-4b12-8cb9-9f7e26703b26, version:0.10.0.2.3.0.0-2557)], nimbus_uptime_secs:0, topologies:[])

Switching back to 0.9.1-incubating showed, that the code still works fine there.
