Description

Using non-deterministic UDFs like rand() in certain expressions that don't reference columns can hit an IllegalStateException. I hit this on commit b9034ea0d54ad40e11b482b577362ceee3768f1e

[tarmstrong-box.ca.cloudera.com:21000] > explain select * from functional.alltypes where rand() > 100 limit 5;
Query: explain select * from functional.alltypes where rand() > 100 limit 5
ERROR: IllegalStateException: null
