Description

DropTableWithViewsIT.testDropTableWithChildViews is flapping again. I see PHOENIX-5074 fixed this test so that the task is run immediately, but somehow this test is still intermittently failing.

This has caused recent preCommit failures for PHOENIX-5981 (build 4010) and
PHOENIX-5984 (build 4011).

When I run this test locally, it passes sometimes and fails sometimes. This is the relevant stack trace:

java.lang.AssertionError
	at org.junit.Assert.fail(Assert.java:87)
	at org.junit.Assert.assertTrue(Assert.java:42)
	at org.junit.Assert.assertFalse(Assert.java:65)
	at org.junit.Assert.assertFalse(Assert.java:75)
	at org.apache.phoenix.end2end.DropTableWithViewsIT.testDropTableWithChildViews(DropTableWithViewsIT.java:158)

Failure is observed in this assertion. I also see that the test sometimes fails because it expects task status to be COMPLETED, but sees status to be STARTED instead.
