------------------------------------

             Summary: binstorage fails to write biginteger
                 Key: PIG-4506
                 URL: https://issues.apache.org/jira/browse/PIG-4506
             Project: Pig
          Issue Type: Bug
          Components: data, impl
            Reporter: Savvas Savvides


When trying to store a biginteger using binstorage the following error is issued (The error might manifest elsewhere too):
java.lang.RuntimeException: Unexpected data type -1 found in stream

This is caused by a bug in the writeDatum method of the DataReaderWriter.java class. When writeDatum is called with a BigInteger as a argument, the BigInteger is converted to a byte[] and the writeDatum method is recursively called on the byte[]. writeDatum cannon handle byte[] objects but instead expects DataByteArray objects.

Suggested fix - wrap byte[] to DataByteArray:
change this line:
_writeDatum(out, ((BigInteger)val).toByteArray());_
to this:
_writeDatum(out, new DataByteArray(((BigInteger)val).toByteArray()));_
