-----------------------------------------------------------------
It was because of some old force push.. Now I changed my git local commit
repo.. Hope it wont come with later commits from me. In commit history diff it
shows as trivial merge only.. No extra unwanted change any way.
Sorry for this

> Project: HBase
> Issue Type: Sub-task
> Components: Offheaping
> Affects Versions: 2.0.0

>
> Introduced by 2.0.0's off-heap feature, the interface RegionScanner extends a
> new interface Shipper which contains a "shipped()" method.
> In our case, some application user defined customized scanner that implements
> Interface RegionScanner in 1.X .
> After we back ported the Off Heap feature of 2.0.0,
> RegionScannerShippedCallBack throws a "java.lang.AbstractMethodError" when
> executing scanner.shipped(). It is because the customized scanner didn't
> override the shipped method yet.
> Instead of forcing every user to add a empty implementation(if they don't
> really need to scan the file or the RS don't use L2 cache, they don't need to
> do anything in shipped method) , adding a default method of shipped in
> Interface RegionScanner might be a better way.
