Minor Description
Here's some minor cleanup in TestMetastoreExpr.
0. There was an incomplete refactor in ExprBuilder.fn(), where the TypeInfo object was hard-coded to booleanTypeInfo.
1. I've removed the throws clauses for redundant exceptions.
2. Expected exceptions have been labelled as ignore.
As an aside, that ExprBuilder is nifty. It's just the thing to exercise HiveMetastoreClient.listPartitionsByExpr(). I'm whacking this idea for an upcoming fix to HCatClient.dropPartitions().
