Looks like this issue is flaky. 😟

I'm going to leave this open and stop commenting.

A human should fix and close this.

When run at the same commit (1e51285), this test passed in one build (Build Status, Sponge) and failed in another build (Build Status, Sponge).

doc(samples): use operation to ensure createion completed

doc(samples): use operation to ensure creation completed

doc(samples): use operation to ensure creation completed (#356)

Oops! Looks like this issue is still flaky. It failed again. 😬

I reopened the issue, but a human will need to close it again.

doc(samples): increase timeouts for instance/cluster creation

@kolea2

This failure is not (as I had earlier assumed) fixable by polling the LRO returned from Cluster.create with a long-enough timeout. Rather, it is being raised directly from the CreateCluster API, before the LRO is constructed. That API has no retry semantics configured in the proto, which means we can't expect it to be retried automagically.

instanceadmin.py:158: in add_cluster
    cluster.create()
../../google/cloud/bigtable/cluster.py:301: in create
    "cluster": cluster_pb,
../../google/cloud/bigtable_admin_v2/services/bigtable_instance_admin/client.py:1001: in create_cluster
    response = rpc(request, retry=retry, timeout=timeout, metadata=metadata,)

None of the API-invoking Cluster and Instance CRUD methods expose retry or timeout parameters, which means that we can't even add a custom retry in the sample to fix this flake. @kolea2 should we update them to allow such usage?

@kolea2

@kolea2 Seeing that samples for other API clients (automl, datalabeling, translate) are using the backoff library, I guess we could update the samples which flake here (particularly adding a cluster to a newly-created instance) to use it, e.g.:

import backoff

...

    @backoff.on_exception(backoff.expo, exceptions.ServiceUnavailable)
    def do_create_cluster(cluster):
        return cluster.create()

    operation = do_create_cluster(cluster)
    operation.result(timeout=30)

doc(samples): add backoff to cluster creation sample

doc(samples): wrap backoff around cluster creation sample

test(samples): add backoff to cluster creation sample (#362)
