Olga Natkovich commented on PIG-560:
------------------------------------
We know that since we put this changes into the production, only one other
person complained so we are pretty certain it is a very rare case. I agree with
Alan that we should only pay the penalty on long strings
> UTFDataFormatException (encoded string too long) is thrown when storing
> strings > 65536 bytes (in UTF8 form) using BinStorage()

> 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).
