Resolution: Not A Problem
Release Note: It was user error.
> Jython UDF invocation failure when importing java class in Cluster mode
> -----------------------------------------------------------------------

> Key: PIG-3376
> URL: https://issues.apache.org/jira/browse/PIG-3376
> Project: Pig
> Issue Type: Bug
> Affects Versions: 0.11
> Environment: local, cluster
> Reporter: Sergey
>
> Hi, I'm testing my scripts in local mode then I run them in production using
> oozie.
> Locally everything works fine. My pig version is 0.11
> When I run the same script in cluster mode, I do get exception on line where
> jython udf is invoked. Here is my UDF, see it imports java class. This class
> is IN runtime, I give 100%:
> {code}
> from ru.pig.geo import GSMCellCalculator
> @outputSchema("centerLon:double, centerLat:double")
> def calculateDropShapedCenter(lon, lat, maxDist, angleWidth, azimuth):
> print lon, lat, maxDist, angleWidth, azimuth
> spatialCoord = GSMCellCalculator.getDropShapeCenter(lon, lat,
> float(maxDist), float(angleWidth), float(azimuth))
> return spatialCoord.longitude, spatialCoord.latitude
> {code}
> Here is a part of script:
> {code}
> register '$geoSpatialUdfs' using jython as udf;
> /*
> some code goes here....
> */
> gsmCellProj = FOREACH gsmCellFixed GENERATE
> branchId,
