Peter Cseh commented on OOZIE-2777:
-----------------------------------

Thanks for the review [~qwertymaniac]!
I've removed the imports and added comments about the old format. The null 
value check may come in handy for different implementations of DataOutput. 
I don't think checking the size of the byte array is necessary. I don't know 
what would be a good upper limit and for negative values, we'll fail anyways.

> Config-default.xml longer than 64k results in  java.io.UTFDataFormatException

> OOZIE-1642 introduced a workaround for DataOutputStream's 64k limit for 
> Strings.
> We've encountered the same error when a config-default.xml is larger than the 
> limit.
