Johannes Zillmann updated PIG-111:
----------------------------------
Attachment: PIG-111_v_11.patch
Hi Pi,
sorry i let you alone with this, but i was very busy doing other stuff...
I applied you lates patch on the latest trunk and did following:
* fixed a bug in HDataStorage where a created exception was actually not thrown.
* fixed the creation of the PigServer in TestStreaming. (Creating the PigServer
for execution mode MAPRED and using the miniCluster requires to pass the
miniClusters properties to the PigServer.
For me the TestStreaming works now!)
* did a change on PigServer constructor's regarding the load of the properties
from file (they get now only loaded from file if they are not passed in as
argument. Please Review!)

> This JIRA discusses issues relating to the configuration of Pig.
> Uses cases:
>
> 1. I want to configure Pig programatically from Java
> Motivation: pig can be embedded from another Java program, and configuration
> should be accessible to be set by the client code
> 2. I want to configure Pig from the command line
> 3. I want to configure Pig from the Pig shell (Grunt)
> 4. I want Pig to remember my configuration for every Pig session
> Motivation: to save me typing in some configuration stuff every time.
> 5. I want Pig to remember my configuration for this script.
> Motivation: I must use a common configuration for 50% of my Pig scripts -
> can I share this configuration between scripts.
> Current Status:
> * Pig uses System properties for some configuration
> * A configuration properties object in PigContext is not used.
> * pigrc can contain properties
> * Configuration properties can not be set from Grunt
> Proposed solutions to use cases:
> 1. Configuration should be set in PigContext, and accessible from client code.
> 2. System properties are copied to PigContext, or can be specified on the
> command line (duplication with System properties)
> 3. Allow configuration properties to be set using the "set" command in Grunt
> 4. Pigrc can contain properties. Is this enough, or can other configuration
> stuff be set, eg aliases, imports, etc.
> 5. Add an include directive to pig, to allow a shared configuration/Pig
> script to be included.
> Connections to Shell scripting:
> * The source command in Bash allows another bash script file to be included
> - this allows shared variables to be set in one file shared between a set of
> scripts.
> * Aliases can be set, according to user preferences, etc.
> * All this can be done in your .bashrc file
> Issues:
> * What happens when you change a property after the property has been read?
> * Can Grunt read a pigrc containing various statements etc before the
> PigServer is completely configured?
