Upgrading Lucene 2.2 to Lucene 3.0.0
-------------------------------------
Key: HBASE-2107
URL: https://issues.apache.org/jira/browse/HBASE-2107
Project: Hadoop HBase
Issue Type: Improvement
Reporter: Kay Kay
HBase has an utility to export columns as Lucene indices.
(o.a.h.hbase.mapreduce.BuildTableIndex ) .
This patch increases the version in libraries.properties and addresses some
deprecations towards moving it.
Rationale for upgradation:
====================
A lot has been happening in the Lucene since 2.2, with improved performance and
focus on NRT (Near Real Time search) happening recently. Hence - we need to
keep up with the same and make the utility publish indices for the new version.
Caveats:
=======
Index created by Lucene 3.0 is *not backward-compatible* with Lucene 2.2 code.
In other words - as part of this upgradation - indices need to be created all
over again and the library interacting with the index ( readers / searchers )
need to be upgraded to the new version as well.
