This turned out to be a result of multiple versions of apache http components.
I made sure my code used the same version of dependencies as the HBase instance
we had.

Subject: Metric sink client keeps crashing the components with SSL-related
exception
This is really not an HBase issue but rather hadoop metrics issue (and it may
not be that either) but I'll just post here to see if someone knows why this is
happening.
I've created a new Metrics2 Sink which will send the metrics over http to some
server.
I can test this locally with no issues. However as soon as we place this in
HBase, we get the following error:
2017-02-14 12:03:01,407 ERROR [main] master.HMasterCommandLine: Master exiting

at com.bing.hadoop.metrics.MdmSink.init(MdmSink.java:37)
I have not even set the URL yet and my url is plain http and not https. I don't
want SSL at all in this case.
Here's my construction code:
public MdmServiceClient(String server, int port) throws Exception {
HttpClientConnectionManager connectionManager = new
BasicHttpClientConnectionManager();
_httpClient =
HttpClientBuilder.create().setConnectionManager(connectionManager).build();
_uri = new
URIBuilder().setScheme("http").setHost(server).setPort(port).setPath("/metrics").build();
}
Line 30 refers to new BasicHttp...
This is line 37 in MdmSink:
_mdmClient = new MdmServiceClient(server, port);
thanks
