Test failure - io.druid.server.lookup.PollingLookupTest.testApplyAfterDataChange

[drcrallen]

As per #3476 (comment) the tests in io.druid.server.lookup.PollingLookupTest are randomly failing

The message for me was different with #3476 (comment)

io.druid.server.lookup.PollingLookupTest
testApplyAfterDataChange[1](io.druid.server.lookup.PollingLookupTest)  Time elapsed: 0.456 sec  <<< ERROR!
java.lang.Exception: test timed out after 300 milliseconds
    at java.lang.Thread.sleep(Native Method)
    at io.druid.server.lookup.PollingLookupTest.testApplyAfterDataChange(PollingLookupTest.java:149)

Believed to be fixed by #3489.
