java.lang.IllegalStateException: Neither Jetty ALPN nor OpenSSL via netty-tcnative were properly configured

Question

I'm doing a Bigtable + Dataflow project in Scala. Using sbt assembly to build a fat jar. It assembles fine, but I get the following run-time error as soon as I run it:

Exception in thread "main" java.lang.IllegalStateException: Could not find an appropriate constructor for com.google.cloud.bigtable.hbase1_2.BigtableConnection

I've read these questions and tried their suggestions but had no success.

• How to solve "Neither Jetty ALPN nor OpenSSL via netty-tcnative were properly configured"?

• Bigtable error with sbt assembly fat JAR (Neither Jetty ALPN nor OpenSSL are available)

I'm using the following artifacts and versions (for google cloud related libs):

"com.google.cloud.dataflow" % "google-cloud-dataflow-java-sdk-all" % "1.9.0"
"com.google.cloud.bigtable" % "bigtable-hbase-1.2" % "0.9.1"

Some other library I'm importing is dependent on google's protocol buffers lib, and that has originated a conflict, for which the merge strategy I used was discarding bigtable-protos-0.3.0.jar (in favor of grpc-core-proto-0.0.3.jar)

Answer 1

Use "com.google.cloud.bigtable" % "bigtable-hbase-dataflow" % "0.9.5.1" instead of "com.google.cloud.bigtable" % "bigtable-hbase-1.2" % "0.9.1". There's a lot of package renaming that had to be done to make hbase compatible with Dataflow.
