Refactor so we use the immutable, unsynchronized TimeRange when doing
time-based checks at read time rather than use heavily synchronized
TimeRangeTracker; let TimeRangeTracker be for write-time only.
While in here, changed the Segment stuff so that when an immutable
segment, it uses TimeRange rather than TimeRangeTracker too.
M hbase-common/src/main/java/org/apache/hadoop/hbase/io/TimeRange.java
Make allTime final.
Add a includesTimeRange method copied from TimeRangeTracker.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/TimeRangeTracker.java
Change name of a few methods so they match TimeRange methods that do
same thing.
(getTimeRangeTracker, getTimeRange, toTimeRange) add utility methods
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/ImmutableSegment.java
Change ImmutableSegment so it uses a TimeRange rather than
TimeRangeTracker.. it is read-only. Redo shouldSeek, getMinTimestamp,
updateMetaInfo, and getTimeRangeTracker so we use TimeRange-based
implementations instead of TimeRangeTracker implementations.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/MutableSegment.java
Implement shouldSeek, getMinTimestamp, updateMetaInfo, and
getTimeRangeTracker using TimeRangeTracker.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/Segment.java
Make methods that were using TimeRangeTracker abstract and instead
have the implementations do these methods how they want either using
TimeRangeTracker when a mutable segment or TimeRange when an immutable
segment.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/StoreFile.java
Change Reader to use TimeRange-based checks instead of
TimeRangeTracker.

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].
