Good catching !
It necessary to distinguish the IOException and the
`errorHandler.shouldRetryError`, the `errorHandler.shouldRetryError ` has two
cases need to retry, one is this PR described
`BLOCK_APPEND_COLLISION_MSG_SUFFIX` for pushing, and other is
`STALE_SHUFFLE_BLOCK_FETCH` for fetching . Please add some unittests for them.
