Pavel Yaskevich commented on CASSANDRA-3886:
--------------------------------------------
I think we should make objToBB method uniform and return in each case e.g.
{noformat}
private ByteBuffer objToBB(Object o)
{
if (o == null)
return (ByteBuffer)o;
if (o instanceof java.lang.String)
return new DataByteArray((String)o);
if (o instanceof Integer)
return IntegerType.instance.decompose((BigInteger)o);
if (o instanceof Long)
return LongType.instance.decompose((Long)o);
if (o instanceof Float)
return FloatType.instance.decompose((Float)o);
if (o instanceof Double)
return DoubleType.instance.decompose((Double)o);
if (o instanceof UUID)
return ByteBuffer.wrap(UUIDGen.decompose((UUID) o));
return null;
}
{noformat}

> Project: Cassandra
> Issue Type: Bug
> Components: Hadoop
> Affects Versions: 0.8.7
> Reporter: Brandon Williams

> In CASSANDRA-2810, we removed the decompose methods in putNext instead
> relying on objToBB, however it cannot sufficiently handle all types. For
> instance, if longs are loaded and then an attempt to store them is made, this
> causes a cast exception: java.io.IOException: java.io.IOException:
> java.lang.ClassCastException: java.lang.Long cannot be cast to
> org.apache.pig.data.DataByteArray Output must be (key, {(column,value)...})
> for ColumnFamily or (key, {supercolumn:{(column,value)...}...}) for
> SuperColumnFamily
