Review comment:
The `putAllAndVerifyKeysExist` test, added in this PR:
https://github.com/apache/geode-native/pull/784/files
(very nearly?) guarantees a state in which not all metadata buckets are
present on the client, so I kind of expect executing a single-hop function
instead of the `putAll` call in this test code would reproduce. This test has
been _very_ reliable, so I wouldn't expect to have a lot of issues with flaky
behavior with respect to metadata updates.

> Key: GEODE-9576
> URL: https://issues.apache.org/jira/browse/GEODE-9576
> Project: Geode
> Issue Type: Bug
> Components: native client
> Reporter: Jakov Varenina
> Assignee: Jakov Varenina
> Priority: Major
> Labels: pull-request-available
>
> *InternalFunctionInvocationTargetException: Multiple target nodes found for
> single hop operation* occurs on native client when executing function in a
> single hop manner for all buckets during the period when client bucket
> metadata doesn't contain all buckets locations.
> Java client in this case executes functions in non single hop manner until it
> receives locations of all buckets on servers. The solution in native client
> would be to implement the same handling as in java client.
