Removes the closeRegion flag added by HBASE-23181 and instead relies on reading meta WALEdit content. Modified how qualifier is written when the meta WALEdit is for a RegionEventDescriptor so the 'type' is added to the qualifer so can figure type w/o having to deserialize protobuf value content: e.g. HBASE::REGION_EVENT::REGION_CLOSE Added doc on WALEdit and tried to formalize the 'meta' WALEdit type and how it works. Needs complete redo in part as suggested by HBASE-8457. Meantime, some doc and cleanup. Also changed the LogRoller constructor to remove redundant param. Because of constructor change, need to change also TestFailedAppendAndSync, TestWALLockup, TestAsyncFSWAL & WALPerformanceEvaluation.java Signed-off-by: Duo Zhang <zhangduo@apache.org> Signed-off-by: Lijin Bin <binlijin@apache.org> |

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. See the export control notice here [9]. 1. http://hbase.apache.org 2. http://research.google.com/archive/bigtable.html 3. http://hadoop.apache.org 4. http://www.apache.org/dyn/closer.lua/hbase/ 5. https://hbase.apache.org/source-repository.html 6. https://hbase.apache.org/issue-tracking.html 7. http://hbase.apache.org/license.html 8. http://hbase.apache.org/mail-lists.html 9. https://hbase.apache.org/export_control.html
