BytesWritable#getBytes is a bad name that leads to programming mistakes
-----------------------------------------------------------------------
Key: HADOOP-6298
URL: https://issues.apache.org/jira/browse/HADOOP-6298
Project: Hadoop Common
Issue Type: Improvement
Affects Versions: 0.20.1
Reporter: Nathan Marz
Pretty much everyone at Rapleaf who has worked with Hadoop has misused
BytesWritable#getBytes at some point, not expecting the byte array to be
padded. I think we can completely alleviate these programming mistakes by
deprecating and renaming this method (again) to be more descriptive. I propose
"getPaddedBytes()" or "getPaddedValue()". It would also be helpful to have a
helper method "getNonPaddedValue()" that makes a copy into a non-padded byte
array.
