Bhooshan Mogal commented on PIG-3441:
-------------------------------------
Thanks. Yes, I tried https://issues.apache.org/jira/browse/PIG-3135 before. I
had a email thread with Prashant regarding this issue. PIG-3135 is for allowing
pig to use standard configuration files (core-site, hdfs-site) from a different
location. This issue is regarding custom configuration files that one may wish
to use. One of the usecases could be the one I mentioned in the description,
where a hadoop driver for a storage system (MyFileSystem.java) loads its own
configuration files statically. Parameters from configuration files loaded
statically in such scenarios are not available in pig scripts/grunt shell.
Here is a link to the email thread for more context -

> Allow Pig to use default resources from Configuration objects
> -------------------------------------------------------------
>
> Key: PIG-3441
> URL: https://issues.apache.org/jira/browse/PIG-3441
> Project: Pig
> Issue Type: Bug
> Components: impl
> Affects Versions: 0.11.1
> Reporter: Bhooshan Mogal
> Attachments: PIG-3441_1.patch, PIG-3441.patch
>
>
> Pig currently ignores parameters from configuration files added statically to
> Configuration objects as Configuration.addDefaultResource(filename.xml).
> Consider the following scenario -
> In a hadoop FileSystem driver for a non-HDFS filesystem you load properties
> specific to that FileSystem in a static initializer block in the class that
> extends org.apache.hadoop.fs.Filesystem for your FileSystem like below -
> {code}
> class MyFileSystem extends FileSystem {
> static {
> Configuration.addDefaultResource("myfs-default.xml");
> Configuration.addDefaultResource("myfs-site.xml");
> }
> }
> {code}
> Interfaces like the Hadoop CLI, Hive, Hadoop M/R can find configuration
> parameters defined in these configuration files as long as they are on the
> classpath.
> However, Pig cannot find parameters from these files, because it ignores
> configuration files added statically.
> Pig should allow users to specify if they would like pig to read parameters
> from resources loaded statically.
