> This need running in cluster:
> 1. Create a hive external table pointing to a hbase table.
> 2. Create views to the hive table(for example 30 views), each view looks like following
with different range check:
> CREATE VIEW hview_nn AS SELECT * FROM hivehbasetable WHERE (pk >='pk_nn_0' AND pk
<= pk_nn_A')
> 3. Create same number of hive new tables as views.
> 4. then runs several queries in parallel (30 threads):
> INSERT OVERWRITE TABLE hivenewtable_nn SELECT * FROM hview_nn   //nn is from 01 to 30
> 5 After insert, check the hivenewtables, some values are not right.
