Description

The following script run on the grid executes correctly. It prints (4L) for '/user/gmavr/k_sample_preprocessed_withj_sample'

On local mode (invoked with -x local) and the same data in the local filesystem, it failes with:

%declare k_sample_preprocessed_withj '/user/gmavr/k_sample_preprocessed_withj_sample';
– %declare k_sample_preprocessed_withj '/homes/gmavr/mlrSite/k_sample_preprocessed_withj_sample';

webdataFiltered = LOAD '$k_sample_preprocessed_withj' USING BinStorage() AS (url:chararray, pg:bytearray);

X1 = GROUP webdataFiltered ALL;
Y1 = FOREACH X1 GENERATE COUNT;
DUMP Y1;
