Implement a rate limiter for the normalizer. Implemented in terms of
MB/sec of affacted region size (the same metrics used to make
normalization decisions). Uses Guava `RateLimiter` to perform the
resource accounting. `RateLimiter` works by blocking (uninterruptible
😖) the calling thread. Thus, the whole construction of the normalizer
subsystem needed refactoring. See the provided `package-info.java` for
an overview of this new structure.
Introduces a new configuration,
`hbase.normalizer.throughput.max_bytes_per_sec`, for specifying a
limit on the throughput of actions executed by the normalizer. Note
that while this configuration value is in bytes, the minimum honored
valued `1_000_000`. Supports values configured using the
human-readable suffixes honored by `Configuration.getLongBytes`

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] Apache HBase is made available under the Apache License, version 2.0 [7] The HBase mailing lists and archives are listed here [8]. The HBase distribution includes cryptographic software.
