---------------------------------------------------------
Commit abf6f8f465e6b99fdd0a97e12bbde143ef98f3db in impala's branch
refs/heads/master from [~philip]
[ https://git-wip-us.apache.org/repos/asf?p=impala.git;h=abf6f8f ]
Fix TestKuduOperations tests in test-with-docker by using consistent hostname.
TestKuduOperations, when run using test-with-docker, failed with errors
like:
Remote error: Service unavailable: Timed out: could not wait for desired
snapshot timestamp to be consistent: Tablet is lagging too much to be able to
serve snapshot scan. Lagging by: 1985348 ms, (max is 30000 ms):
The underlying issue, as discovered by Thomas Tauber-Marshall, is that Kudu
serializes the hostnames of Kudu tablet servers, and, different containers in
test-with-docker use different hostnames. This was exposed after "IMPALA-6812:
Fix flaky Kudu scan tests" switched to using READ_AT_SNAPSHOT for Kudu reads.
Using the same hostname for all the containers is easy and harmless;
this change does just that.
