I was able to work out all of my compilation issues; however when I run an integration test with the Mini Accumulo Cluster that tests writing mutations with values of 5mb the flush hangs forever and I see the following logs in the TabletServer logs:
20:41:02.306 [Thread-7] ERROR o.a.a.s.r.CustomNonBlockingServer$CustomFrameBuffer - Read a frame size of 18874697, which is bigger than the maximum allowable frame size 16384000 for ALL connections. 20:41:03.582 [Thread-7] ERROR o.a.a.s.r.CustomNonBlockingServer$CustomFrameBuffer - Read a frame size of 18874697, which is bigger than the maximum allowable frame size 16384000 for ALL connections. 20:41:05.079 [Thread-7] ERROR o.a.a.s.r.CustomNonBlockingServer$CustomFrameBuffer - Read a frame size of 18874697, which is bigger than the maximum allowable frame size 16384000 for ALL connections. Other tests that write smaller amounts of data appear to work fine. Any idea what the issue might be?
