Mingliang Liu updated HADOOP-10823:
-----------------------------------
Attachment: HADOOP-10823.001.patch
This test is flaky and fails recently, e.g. [HADOOP-13444] and [HADOOP-13297].
I think increasing the sleep time is not ideal. According to the [Über-jira
proposal|HDFS-10666], we should not use fixed sleep interval to wait for
conditions. To address this, one approach is to coordinate the test thread and
the reloader thread which, however, needs intrusive changes in the production
code. A better solution is to trigger the configuration reload manually in
test. We can achieve this by changing the modification time of the trust store
file. After that, we can use {{GenericTestUtils.waitFor()}} to retry the
assertion. I attached the v1 patch for addressing this.
[~rdsr], thoughts? Ping [~arpitagarwal] and [~jnp] for more input. Thanks.
