How to setup proxy for FlightClient class

[NguyenHoangSon96]

Describe the usage question you have. Please include as many useful details as possible.

Hi guys
I'm using FlightClient class, but I need to use proxy.
I can't find any way to inject HttpConnectProxiedSocketAddress into FlightClient

Just to be sure I understand correctly: you can to use a proxy in the FlightClient (not creating your own proxy). Correct ?

Hi @jbonofre
Thanks for looking into this
Yes, I want to use HttpConnectProxiedSocketAddress for proxy

Set up a gRPC channel yourself and then use

arrow-java/flight/flight-core/src/main/java/org/apache/arrow/flight/FlightGrpcUtils.java

Lines 143 to 152 in 045249a

	/**
	* Creates a Flight client.
	*
	* @param incomingAllocator Memory allocator
	* @param channel provides a connection to a gRPC server.
	*/
	public static FlightClient createFlightClient(
	BufferAllocator incomingAllocator, ManagedChannel channel) {
	return new FlightClient(incomingAllocator, channel, Collections.emptyList());
	}

@lidavidm that was my question to @NguyenHoangSon96 : is he ready to define his own FlightClient or is he expecting to "inject" the proxy.

[lidavidm]

You will still get a FlightClient, though.

Otherwise, I'm not sure what the question even is here

Hi @lidavidm, @jbonofre
Thank you for look into this
Currently I'm doing like this. But It still ignore the proxy for some reason
Did I using the ProxyDetector correct?

Yes, I'm also a bit confused by the question 😄

[lidavidm]

That seems mostly like a gRPC question, it might be best to ask the gRPC community there

[NguyenHoangSon96]

Ok, I will ask them
Thank you guys for the help
