Description

The HIVE_VECTORIZATION_GROUPBY_COMPLEX_TYPES_ENABLED is definied like this:

HIVE_VECTORIZATION_GROUPBY_COMPLEX_TYPES_ENABLED("hive.vectorized.groupby.complex.types.enabled", true,
    "This flag should be set to true to enable group by vectorization\n" +
    "of aggregations that use complex types.\n",
    "For example, AVG uses a complex type (STRUCT) for partial aggregation results" +
    "The default value is true."),

Notice that the end of the "of aggregations that use complex types.\n" line is a "," instead of "+".

So this will end up using the following constructor using the second sentence as an "altName"

    ConfVars(String varname, Object defaultVal, String description, String altName) {
      this(varname, defaultVal, null, description, true, false, altName);
    }

We should fix this.
