8b2bd18c6624301ad45ce361c90bfd29691afea7 [client-test] fix TestFailedDnsResolution
I noticed that ClientTest.TestFailedDnsResolution fails unexpectedly
with the following error when running on macOS:
src/kudu/client/client-test.cc:3205: Failure
Value of: s.IsIOError()
Actual: false
Expected: true
unexpected status: OK
It turned out that the scenario didn't expect that
(a) the results of DNS resolution are cached
(b) a tablet server's address can be the same as master's
(a) turned true with changelist 48467ccf4, and (b) is true in case of
running test mini-cluster with other than UNIQUE_LOOPBACK bind mode:
e.g., on macOS it's run in LOOPBACK mode.
I updated the scenario to use a non-caching DNS resolver. I also
increased the timeout for write operations because the scenario
was failing from time to time in case TSAN builds. In addition, since
timeouts in GetTableLocations RPC are reported two-fold due to the
client's metacache activity, the test was failing rarely due to
receiving other non-expected error message. I updated the list of
expected error messages to add the missing case.
With this patch, the scenario succeeds on macOS and runs more stable
for Linux TSAN builds.
