Obviously this is user error, but we should be protecting against this.

Looks like the issue could be line 154 in DDF_RxInstrumentProvider

Here is a test case

Iterator<Result<Instrument>> res = marketerDDF.getClient().instrument(new String[] { "AAPL", null }).toBlockingObservable().getIterator();

log.warn("res.hasNext() = " + res.hasNext()); // blocks here
log.warn("res.next() = " + res.next());

To repo, run the HistoricalEODExample and add the below after line 110

result.getQuery();

Hello,

Thanks for sharing the libraries.

I could not find anything here on how to use the recovery url when the feed gets disconnected.

Any suggestions on how to handle such scenarios?

Thanks
