[jira] Updated: (PIG-69) NullPointerException in setJobtrackerLocation() in PigContext.java:68

["Benjamin Francisoud (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/PIG-69?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Benjamin Francisoud updated PIG-69:
-----------------------------------

    Attachment: PigContext-PIG-69-v01.patch

This patch fix the null pointer and allows at the same time to set more configuration parameters using IoC approach.

The problem with setting conf param with methods like "setJobtrackerLocation()" and "setFilesystemLocation()" is that you will end up adding lots of those methods filling the class with boiler plate code for each parameter :(

The client code will look like:
{code:java}
PigContext pigContext = new PigContext(ExecType.MAPREDUCE);
JobConf conf = new JobConf(configuration);
pigContext.setConf(conf);

PigServer pigServer = new PigServer(pigContext);
{code}

This patch makes setJobtrackerLocation() and setFilesystemLocation() deprecated.
