> When using a custom load/store function, one that returns complex data (map
> of maps, list of maps), for certain sequences of LOAD, FILTER, FOREACH pig
> script throws an exception of the form -
>
> org.apache.pig.backend.executionengine.ExecException: ERROR 1075: Received a
> bytearray from the UDF. Cannot determine how to convert the bytearray to
> <actual-type>
> at
> org.apache.pig.backend.hadoop.executionengine.physicalLayer.expressionOperators.POCast.getNext(POCast.java:639)
> ...
> Looking through the code of POCast, apparently the operator was unable to
> find the right load function for doing the conversion and consequently bailed
> out with the exception failing the entire pig script.
