How to connect to a running bigtable emulator from java -


i trying use bigtable emulator gcloud beta emulators. launch emulator, grab hostname (localhost) , port (in instance 8885)

gcloud beta emulators bigtable start

executing: /usr/local/caskroom/google-cloud-sdk/latest/google-cloud-sdk/platform/bigtable-emulator/cbtemulator --host=localhost --port=8885

i trying connect emulator java test client, here provide:

configuration conf = bigtableconfiguration.configure(projectid, instanceid);  if(!strings.isnullorempty(host)){     conf.set(bigtableoptionsfactory.bigtable_host_key, host);     conf.set(bigtableoptionsfactory.bigtable_port_key, integer.tostring(port)); } connection = bigtableconfiguration.connect(configuration); try (table table = connection.gettable("tname")){     table.put(<put instance>); }

when execute test code get:

16:36:37.369 [bigtable-batch-pool-1] info com.google.cloud.bigtable.grpc.async.abstractretryingrpclistener - retrying failed call. failure #1, got: status{code=unavailable, description=null, cause=java.net.connectexception: connection refused: localhost/0:0:0:0:0:0:0:1:8885} java.net.connectexception: connection refused: localhost/0:0:0:0:0:0:0:1:8885

i using library: com.google.cloud.bigtable:bigtable-hbase-1.2:0.9.1

any idea of doing wrong ?

thanks !

you need 1 additional config property set:

conf.set(bigtableoptionsfactory.bigtable_use_plaintext_negotiation, true);

also, log message looks it's trying connect ipv6 address, don't think work. double-check host valid ipv4 address.

the java client make easier in near future.
