Description
A job is failing with reduce tasks failed to fetch map output and the NodeManager ShuffleHandler failed to serve the map outputs with some IOException like below. ShuffleHandler sends the actual error message in response inside sendError() but the Fetcher does not log this message.
Logs from NodeManager ShuffleHandler:
