> We now completely ignore token renewal failures. For things like Timeline tokens which are automatically obtained whether the app needs it or not (we should fix this to be user driven), we can ignore failures. But for HDFS Tokens etc, ignoring failures is bad because it (1) wastes resources as AMs will continue and eventually fail (2) app doesn't know what happened it fails eventually.
