> Hive compiler fails with a NullPointerException in semantic analysis /
> optimisation stage when a boolean variable appears in the WHERE clause in
> some cases. A minimal query to generate this error is here:
> SELECT 1
> FROM (
> SELECT TRUE AS flag
> FROM dim_one_row:measurementsystems
> ) a
> WHERE flag;
> On the other hand, the following query is perfectly fine:
> SELECT 1
> FROM (
> SELECT TRUE AS flag
> FROM dim_one_row:measurementsystems
> ) a
> WHERE flag=TRUE;
