Timeouts are not configurable for RPC about hdfs HOT 5 CLOSED

Hi @peay,

Good point - this should definitely be configurable. This dovetails well with the need for a configurable dialer in #70.

from hdfs.

With #77, there now exists a ClientOptions struct, so this should now be implementable.

@colinmarc Any update for this issue, i also got error: dial tcp: i/o timeout. After modifying the value to 3, the real error is hostname cannot be resolved. This is beacause the datanodes' hostnames are not being registed into my company's DNS server.

I'm working on a rework of timeouts. But it doesn't sound like your issue is timouts, @Itfly; it sounds like your datanode hosts aren't resolvable from the client. If you fix your DNS setup it should work.

@colinmarc Yes it works after i adding the datanode host to our company's DNSSelfService. However, i suggest to make it configurable about using hostname or ip address (#123)
