Hello Alexey Serbin, Kudu Jenkins,
I'd like you to reexamine a change. Please visit
http://gerrit.cloudera.org:8080/11523
to look at the new patch set (#2).
Change subject: create-table-stress-test: deflake
TestConcurrentCreateTableAndReloadMetadata
......................................................................
create-table-stress-test: deflake TestConcurrentCreateTableAndReloadMetadata
First, if the ASSERT_OK fired, the test would hang. No bueno.
Second, in TSAN environments the test would sometimes fail with a table
already present error, typically happening either 30s or 60s after that
table was created. I believe this is due to a client-side timeout _after_
the table was created but _before_ its RPC response was sent. We could
try to address this by bumping the client's timeout, but because
reload_metadata_thread is DoS'ing the cluster, that doesn't seem robust.
Instead, let's have the thread ease up in TSAN environments.
Without the change, the test failed 4/1000 times (--stress_cpu_threads=4).
With the change, the test failed 0/1000 times (--stress_cpu_threads=8).
