Log:
HIVE-1487 [jira] Add ptest script
(Marek Sapota via John Sichi)

Summary: HIVE-1464 speeded up serial runs somewhat - but looks like it's still
too slow. we should use parallel junit or some similar setup to run test queries
in parallel. this should be really easy as well need to just use a separate
warehouse/metadb and potentiall mapred system dir location.

Test Plan: EMPTY

+= Configuration file =
+
+Configuration file is JSON formated, example:
+
+{
+    "qfile_hosts": [
+        ["hostname1", 2],
+        ["hostname2", 4],
+        ["hostname3", 4],

+    "host_base_path": "/mnt/drive/hivetests"
+    "java_home": "/opt/jdk"
+}
+
+== qfile_hosts ==
+List of hosts that should run TestCliDriver and TestNegativeCliDriver test
+cases.  Number following the host name is number of simultaneous tests that
+should be run on this host, you should probably set it near number of cores that
+host has.
+
+== other_hosts ==
+List of hosts that should run all other test cases.  Number has the same meaning
+as in `qfile_hosts`.
+
+== master_base_path ==
+Path on localhost (master) where this script can build Hive, store reports, etc.
+This path should be available from every slave node and should point to the same
+data (home on NFS would be a good choice).
+
+== host_base_path ==
+Path on slaves where Hive repo will be cloned and tests will be run.
+'-your_user_name' will be actually appended to this path to allow parallel runs
+by different users.
+
+== java_home ==
+Should point to Java environment that should be used.
+
+== About paths ==
+You can use environmental variables with `${{my_env}}`, as home is used in the
+example.
+
+You shouldn't point this paths to your work repository or any directory that
+stores data you don't want to lose.  This script might wipe everything under
+`master_base_path` and `host_base_path` as needed.
