Christopher,

I am not sure if this issue is related to 3042 or not.

On the client side it does look like TConfiguration ends up being called
with the default constructor.  I am not sure if this is intentional or not.

On the server side I see this stack, so it also looks like:

at org.apache.thrift.TConfiguration.<init>(TConfiguration.java:36)
at org.apache.thrift.TConfiguration$Builder.build(TConfiguration.java:99)
at org.apache.thrift.TConfiguration.<clinit>(TConfiguration.java:65)
at
org.apache.thrift.transport.TNonblockingSocket.<init>(TNonblockingSocket.java:74)
at
org.apache.thrift.transport.TNonblockingSocket.<init>(TNonblockingSocket.java:68)
at
org.apache.thrift.transport.TNonblockingServerSocket.accept(TNonblockingServerSocket.java:135)
at
org.apache.thrift.transport.TNonblockingServerSocket.accept(TNonblockingServerSocket.java:36)
at
org.apache.thrift.server.TNonblockingServer$SelectAcceptThread.handleAccept(TNonblockingServer.java:218)
at
org.apache.thrift.server.TNonblockingServer$SelectAcceptThread.select(TNonblockingServer.java:186)
at
org.apache.thrift.server.TNonblockingServer$SelectAcceptThread.run(TNonblockingServer.java:142)


I see this in the server log so it does look like it should be using 1G:
2022-09-01 16:59:41 INFO  [org.apache.accumulo.tserver.TabletServer]
ServerUtil:124 - general.server.message.size.max = 1G

Thanks,
Vincent
