This gist includes components of a oozie workflow - scripts/code, sample data 
and commands;  Oozie actions covered: java mapreduce action; Oozie controls 
covered: start, kill, end; The java program uses regex to parse the logs, and
also extracts the path of the mapper input directory path and includes in the 
key emitted.

Note: The reducer can be specified as a combiner as well.
 
Usecase
-------

airawat

This gist includes components of a simple workflow application (oozie 3.3.0) that 
pipes data in a Hive table to mysql; 
 
The sample application includes:
--------------------------------
1.  Oozie actions: sqoop action 
2.  Oozie workflow controls: start, end, and kill. 
3.  Workflow components: job.properties and workflow.xml
4.  Sample data
5.  Prep tasks in Hive

This gist includes components of a simple workflow application that created a directory and moves files within 
hdfs to this directory; 
Emails are sent out to notify designated users of success/failure of workflow.  There is a prepare section, 
to allow re-run of the  action..the prepare essentially negates the move done by a potential prior run 
of the action.  Sample data is also included.

The sample application includes:
--------------------------------
1.  Oozie actions: hdfs action and email action 
2.  Oozie workflow controls: start, end, and kill.

This gist includes components of a oozie, dataset availability initiated, coordinator job - 
scripts/code, sample data and commands;  Oozie actions covered: hdfs action, email action, 
sqoop action (mysql database);  Oozie controls covered: decision;  
 
Usecase
-------
Pipe report data available in HDFS, to mysql database;

This gist includes components of a oozie (trigger file initiated) coordinator job - 
scripts/code, sample data and commands;  Oozie actions covered: hdfs action, email action, 
java main action, hive action;  Oozie controls covered: decision, fork-join; The workflow 
includes a sub-workflow that runs two hive actions concurrently.  The hive table is 
partitioned;  Parsing uses hive-regex serde, and Java-regex.  Also, the java mapper, gets 
the input directory path and includes part of it in the key.
 
Usecase
-------
Parse Syslog generated log files to generate reports;
