NodesInfoRequest: NodeInfo fields mostly null in Elastic 0.19.8 (worked in Elastic 0.18.7)

Elastic Stack Elasticsearch
1

We are getting node information like this:

client.admin().cluster().nodesInfo(new NodesInfoRequest()).get(1, TimeUnit.
MINUTES)

This gives us back a NodesInfoResponse, which we iterate over, getting back
multiple NodeInfo objects.

Now, in Elastic Search 0.18.7, this works:

nodeInfo.getSettings()

But when we upgraded to Elastic Search 0.19.8 it gives us back null.
On debugging, we can see that actually it's not just settings that is null,
most of the fields are also null:

nodeInfo = {org.elasticsearch.action.admin.cluster.node.info.NodeInfo@3101}
serviceAttributes =
{org.elasticsearch.common.collect.SingletonImmutableMap@4631} size = 1
[0] = {org.elasticsearch.common.collect.ImmutableEntry@4676}"http_address"
-> "inet[/123.123.123.123:9978]"
hostname = {java.lang.String@4645}"MYHOSTNAME"
settings = null
os = null
process = null
jvm = null
threadPool = null
network = null
transport = null
http = null
node =
{org.elasticsearch.cluster.node.DiscoveryNode@4646}"[index_node_on_port_9978][SNPervzkSXSEGGv275J7Zw][inet[/123.123.123.123:9977]]{master=true}"
nodeName = {java.lang.String@4680}"index_node_on_port_9978"
nodeId = {java.lang.String@4681}"SNPervzkSXSEGGv275J7Zw"
address =
{org.elasticsearch.common.transport.InetSocketTransportAddress@4682}"inet[/123.123.123.123:9977]"
attributes = {org.elasticsearch.common.collect.SingletonImmutableMap@4683}
size = 1
version = {org.elasticsearch.Version@4684}"0.19.8"

Is this a bug? Or is there some change in the way we must request node
information?
Specifically what we need to get is the tcp port:

nodeInfo.getSettings().get("transport.tcp.port")

Thanks

This is because in 0.19, you need to pass specific flags to get the relevant info you are after. NodeInfoRequest#settings(true), NodeInfoRequest#jvm(true).
