Cloud Bigtable Failure due to NPN/ALPN extensions not installed

Trying to interact with Google Cloud Bigtable via Java lib and after successfully creating connection object, send "list" command and I am getting the following error for command.run() method:

command.run(connection, argsList.subList(1, argsList.size()));

specifically:

Jul 06, 2015 1:12:15 PM io.grpc.transport.netty.ProtocolNegotiators$AbstractBufferingHandler fail
SEVERE: Transport failed during protocol negotiation

Just following;https://cloud.google.com/bigtable/docs/samples-simple-cli

Any help would be highly appreciated!

It is necessary to modify your eclipse java run to load the alpn-boot jar in front of all other classes / jars. Using the line:

-Xbootclasspath/p:$(pwd)/lib/bigtable/alpn-boot-${ALPN_VERSION}.jar

For more information, see ALPN.

For Unit Testing in Maven, you can look at our example

UPDATE You can now work w/o alpn-boot by using the Netty TCNative jar w/ BoringSSL we have two examples with that currently, the Managed-VM-Sample and the Quickstart. See the pom.xml for the details, the MVM sample shows how to setup your pom to compile locally and deploy. The Quickstart pom shows a compile and run on the same machine form. We hope to have all the Java samples using this soon.
