* HBASE-27088 IntegrationLoadTestCommonCrawl async load improvements - Use an async client and work stealing executor for parallelism during loads. - Remove the verification read retries, these are not that effective during replication lag anyway. - Increase max task attempts because S3 might throttle. - Implement a side task that exercises Increments by extracting urls from content and updating a cf that tracks referrer counts. These are not validated at this time. It could be possible to log the increments, sum them with a reducer, and then verify the total, but this is left as a future exercise. Signed-off-by: Viraj Jasani <vjasani@apache.org> * Sum RPC time for writes (loader) and reads (verifier) and mutation bytes submitted. Expose as job counters. * Fix an issue with completion chaining * Pause loading if too many operations are in flight
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.
