Description

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%:

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

Here is a part of script:

register '$geoSpatialUdfs' using jython as udf;
/*
some code goes here....
*/
gsmCellProj = FOREACH gsmCellFixed GENERATE
                                         branchId,
                                         cellId, lac,
                                         lon, lat,
                                         (int)azimuth, (int)midDist, (int)maxDist,
                                         cellType, (int)angWidth, gen, startAng,
                                         angWidthFixed, startAngFixed,
                                         FLATTEN(udf.calculateDropShapedCenter(lon, lat, midDist, angWidth, azimuth));

Here is the log STDOUT:
