Exists api return true but path does not exist

[aluode99]

using Exists api return true when non-ErrNoNode occurs.

_, err := c.request(opExists, &existsRequest{Path: path, Watch: false}, res, nil)
exists := true
if err == ErrNoNode {
exists = false
err = nil
}
return exists, &res.Stat, err

We use Get() instead of Exists() because Exists() doesn't work correctly either for us.

And maybe i know the direct reason (not the real reason) is that we cannot do comparison like below in our own logic:

err == ErrNoNode

Instead, we do

err.Error() == ErrNoNode.Error()

Maybe they are not reused correctly inside though there was a error code map in constants.go

You should ignore all other return values in case non-nil error is returned. The exists return value carries no meaning if an error was present
