Rohini Palaniswamy commented on PIG-4506:
-----------------------------------------
For the test, could you just add biginteger and bigdecimal to
TestEvalPipeline2.testBinStorageByteArrayCastsSimple instead of adding a new
one in TestStore. That is a more logical fit place for the test as it already
tests other datatypes for BinStorage there.

> 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()));_
