             Summary: Intermittent test failures
                 Key: CALCITE-1561

          Issue Type: Bug
            Reporter: Julian Hyde
            Assignee: Julian Hyde


A few tests are currently failing intermittently.

1. UdfTest

{noformat}
UdfTest.testUserDefinedFunction:162 
Expected: is <9>
    but: was <10>
{noformat}

2. StreamTest.testInfiniteStreamsDoNotBufferInMemory

{noformat}
FAILURE! - in org.apache.calcite.test.StreamTest
testInfiniteStreamsDoNotBufferInMemory(org.apache.calcite.test.StreamTest)
Time elapsed: 0.218 sec  <<< ERROR!
java.lang.RuntimeException: exception while executing [select stream * from
orders]

Caused by: java.util.NoSuchElementException

I don't consider any of them serious -- they are test issues, not product correctness issues -- but they are inconvenient because false negatives waste developer time.
