…pache#53186) (apache#53194) If you tried to send a large XCom value, it would fail in the task/child process side with this error: > RuntimeError: unable to read full response in child. (We read 36476, but expected 1310046) (The exact number that was able to read dependent on any different factors, like the OS, the current state of the socket and other things. Sometimes it would read up to 256kb fine, othertimes only 35kb as here) This is because the kernel level read-side socket buffer is full, so that was as much as the Supervisor could send. The fix is to read in a loop until we get it all. (cherry picked from commit b9620bf) Co-authored-by: Ash Berlin-Taylor <ash@apache.org>
