Project: Hadoop Common
Issue Type: Improvement
Components: compress, io
Affects Versions: 3.3.6

On our HBase clusters, while looking at CPU profiles, I noticed that about 1%
of overall CPU cycles are spent under BlockDecompressorStream#rawReadInt just
throwing EOFException. This could be easily avoided.
