Hi,

When I run the query "select count(1) from pokes;" it fails with the message as below.

hive> select count(1) from pokes;

In order to change the average load for a reducer (in bytes):
  set hive.exec.reducers.bytes.per.reducer=<number>
In order to limit the maximum number of reducers:

  set mapred.reduce.tasks=<number>
