No not this. There are 3 other places in this file where it's set. But
still experimenting with this fix. If this works, a new error number will be
generated right after the call to hdfsOpenFile . If errno is EAGAIN or ENOENT,
the new error message will be returned and we will retry based on that error
at the higher layer. But the suggestion to return errno and perhaps also the
filename as an output param may be a good one too. Will consider it.
