Jesus Camacho Rodriguez commented on CALCITE-2953:
--------------------------------------------------
I've realized this... It seems there is some flakiness in {{LatticeTest}}. For
instance, in the [last Travis
run|https://travis-ci.org/apache/calcite/jobs/511278223] two tests failed:
{code}

However, I have run the test several times locally and it does not always fail.
