------------------------------------
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()));_
