> I found a few bits of code copied from guava src:
> {code}
> ./src/main/java/org/apache/hadoop/hbase/io/LimitInputStream.java: * Copied from guava
source code v15 (LimitedInputStream)
> ./src/main/java/org/apache/hadoop/hbase/io/LimitInputStream.java: * allows to be compatible
with guava 11 to 15+.
> ./src/main/java/org/apache/hadoop/hbase/util/ByteBufferUtils.java:         * from guava
v21
> ./src/main/java/org/apache/hadoop/hbase/util/Bytes.java:             * comparator from
guava v21
> {code}
> We can instead point back at guava implementations now we use shaded guava internally.
No point having it in our code base when latest guava is on latest CLASSPATH (This wasn't
always the case; this is why the code was copied into hbase).
> Also, there are other copies other than the above.
