HBASE-26274 Create an option to reintroduce BlockCache to mapreduce job (#3684) 
Introduce `hfile.onheap.block.cache.fixed.size`
and default to disable. when using ClientSideRegionScanner
it will be enabled with a fixed size for caching 
INDEX/LEAF_INDEX block when a client, e.g. 
snapshot scanner, scans the entire HFile
and does not need to seek/reseek to index
block multiple times.

Apache HBase [1] is an open-source, distributed, versioned, column-oriented
store modeled after Google' Bigtable: A Distributed Storage System for
Structured Data by Chang et al.[2]  Just as Bigtable leverages the distributed
data storage provided by the Google File System, HBase provides Bigtable-like
capabilities on top of Apache Hadoop [3].

To get started using HBase, the full documentation for this release can be
found under the doc/ directory that accompanies this README.  Using a browser,
open the docs/index.html to view the project home page (or browse to [1]).
The hbase 'book' at http://hbase.apache.org/book.html has a 'quick start'
section and is where you should being your exploration of the hbase project.

The latest HBase can be downloaded from an Apache Mirror [4].

The source code can be found at [5]

The HBase issue tracker is at [6]

The HBase distribution includes cryptographic software. See the export control
notice here [9].
