             Summary: Make RemoteDriverTest thread-safe
                 Key: CALCITE-687
                 URL: https://issues.apache.org/jira/browse/CALCITE-687
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde
            Assignee: Julian Hyde


There is apparently a thread safety issue in RemoteDriverTest. Here is output from <a href="https://travis-ci.org/julianhyde/incubator-calcite/jobs/58869949">Travis</a>:{code}ests run: 18, Failures: 1, Errors: 0, Skipped: 4, Time elapsed: 29.008 sec <<< FAILURE! - in org.apache.calcite.avatica.RemoteDriverTest
testStatementLifecycle(org.apache.calcite.avatica.RemoteDriverTest)  Time elapsed: 1.807 sec  <<< FAILURE!
java.lang.AssertionError: expected:<1> but was:<9>
	at org.junit.Assert.fail(Assert.java:88)
	at org.junit.Assert.failNotEquals(Assert.java:743)
	at org.junit.Assert.assertEquals(Assert.java:118)
	at org.junit.Assert.assertEquals(Assert.java:555)
	at org.junit.Assert.assertEquals(Assert.java:542)
	at org.apache.calcite.avatica.RemoteDriverTest.testStatementLifecycle(RemoteDriverTest.java:388)
{code} Presumably this occurs in Travis because several tests are running concurrently.

I have disabled the test. We must fix this issue and re-enable the test.
