Elasticsearch to BigQuery pipeline deployment fails on cloud data fusion instance

Question

I am deploying a data fusion pipeline which takes data from an index at elasticsearch and load that data to bigQuery table. Pipeline simply consist of elasticsearch plugin connector to BigQuery connector. When I run the pipeline it generates the following error. Source of the error is

io.cdap.cdap.internal.app.runtime.distributed.remote.RemoteExecutionTwillRunnerService#548-runtime-startup-1

Actual error is

java.io.IOException: com.jcraft.jsch.JSchException: java.net.ConnectException: Connection timed out (Connection timed out)

How can I resolve this issue?

Answer 1

Please see the networking requirements as documented in https://cloud.google.com/data-fusion/docs/how-to/create-instance .

Specifically:

New projects start with a default network. The default network is pre-populated with a firewall rule, default-allow-ssh, that allows incoming connections on TCP port 22 from any source to any instance in the network. If such a rule doesn't exist in the network used by your Cloud Data Fusion instance, you need to create such a rule.
