Description

A few tests are currently failing intermittently.

1. UdfTest

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

2. StreamTest.testInfiniteStreamsDoNotBufferInMemory

FAILURE! - in org.apache.calcite.test.StreamTest

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.
