Description
Every so often I find myself looking at executor logs, wondering why something is going wrong (failed exec, or seems to be stuck etc) and I wish I had a bit more info about shuffle sizes. ShuffleBlockFetcherIterator logs the number of local & remote blocks, but not their sizes. It would be really easy to add in size info too.
eg. instead of
19/01/22 23:10:49.978 Executor task launch worker for task 8 INFO ShuffleBlockFetcherIterator: Getting 2 non-empty blocks including 1 local blocks and 1 remote blocks
it should be
19/01/22 23:10:49.978 Executor task launch worker for task 8 INFO ShuffleBlockFetcherIterator: Getting 2 (194.0 B) non-empty blocks including 1 (97.0 B) local blocks and 1 (97.0 B) remote blocks
I know this is a really minor change, but I've wanted it multiple times, seems worth it.
