Recently, the full data load started failing because Hive ran out of heap space while
writing the nested tpch tables. This patch simply bumps up the heap space, and the query
is now successfull.

Due to a possible change in behaviour in Hive/MR, it is no longer possible to use
arbitrarily large values for parquet.block.size. This breaks the loading of nested tpch
data on newer Hive. This patch addresses the problem by using a permissble value.

When loading a large nested table using the GROUP_CONCAT function,
Impala runs out of memory. We prevent this from happening by adding
an option to partition the table and load one partition at a time.
