> 65536 bytes (in UTF8 form) using BinStorage()

                 Key: PIG-560
                 URL: https://issues.apache.org/jira/browse/PIG-560
             Project: Pig
          Issue Type: Bug
    Affects Versions: types_branch
            Reporter: Pradeep Kamath
             Fix For: types_branch


BinStorage() uses DataOutput.writeUTF() and DataInput.readUTF() Java API to 
write out Strings as UTF-8 bytes and to read them back. From the Javadoc - 
"First, the total number of bytes needed to represent all the characters of s 
is calculated. If this number is larger than 65535, then a 
UTFDataFormatException  is thrown. " (because the writeUTF() API uses 2 bytes 
to represent the number of bytes). A way to get around this would be to not use 
writeUTF()/ReadUTF() and instead hand convert the string to the corresponding 
UTF-8 byte[]  (using String.getBytes("UTF-8") and then write the length of the 
byte array as an int - this will allow a size of upto 2^32 (2 raised to 32).
