>                 Key: HBASE-10422
>                 URL: https://issues.apache.org/jira/browse/HBASE-10422
>             Project: HBase
>          Issue Type: Bug
>          Components: Client, Protobufs
>    Affects Versions: 0.96.1.1, 0.96.1, 0.98.0
>            Reporter: Benoit Sigoure
>         Attachments: 10422-Fix-the-signature-of-zeroCopyGetBytes-to-make-it-us.patch

> In HBASE-9868 the trick that AsyncHBase uses to extract byte arrays from protobufs without
copying them was ported, however the signature of {{zeroCopyGetBytes}} was changed for some
reason.  There are two problems with the changed signature:
> # It makes the helper function unusable since it refers to a package-private class.
> # It clashes with the signature AsyncHBase expects, thereby making user's life miserable
for those who pull in both AsyncHBase and HBase on their classpath.
