This removes the Solr security manager hacks for Hadoop. It does so by: * Using a fake group mapping class instead of ShellGroupMapping * Copies a few Hadoop classes and modifies them for tests with no Shell * Nulls out some of the static variables in the tests The Hadoop files were copied from Apache Hadoop 3.2.0 and copied to the test package to be only picked up during tests. They were modified to remove the need to shell out for access. The assumption is that these HDFS integration tests only run on Unix based systems and therefore Windows compatibility was removed in some of the modified classes. The long term goal is to remove these custom Hadoop classes. All the copied classes are in the org.apache.hadoop package. Signed-off-by: Kevin Risden <krisden@apache.org> |

Apache Lucene and Solr
Apache Lucene is a high-performance, full featured text search engine library written in Java.
Apache Solr is an enterprise search platform written using Apache Lucene. Major features include full-text search, index replication and sharding, and result faceting and highlighting.
Online Documentation
This README file only contains basic setup instructions. For more comprehensive documentation, visit:
Building Lucene/Solr
(You do not need to do this if you downloaded a pre-built package)
Lucene and Solr are built using Apache Ant. To build Lucene and Solr, run:
ant compile
If you see an error about Ivy missing while invoking Ant (e.g., .ant/lib does not exist), run ant ivy-bootstrap and retry.
Sometimes you may face issues with Ivy (e.g., an incompletely downloaded artifact). Cleaning up the Ivy cache and retrying is a workaround for most of such issues:
rm -rf ~/.ivy2/cache
The Solr server can then be packaged and prepared for startup by running the
following command from the solr/ directory:
ant server
Running Solr
After building Solr, the server can be started using
the bin/solr control scripts. Solr can be run in either standalone or
distributed (SolrCloud mode).
To run Solr in standalone mode, run the following command from the solr/
directory:
bin/solr start
To run Solr in SolrCloud mode, run the following command from the solr/
directory:
bin/solr start -c
The bin/solr control script allows heavy modification of the started Solr.
Common options are described in some detail in solr/README.txt. For an
exhaustive treatment of options, run bin/solr start -h from the solr/
directory.
Development/IDEs
Ant can be used to generate project files compatible with most common IDEs. Run the ant command corresponding to your IDE of choice before attempting to import Lucene/Solr.
- Eclipse -
ant eclipse(See this for details) - IntelliJ -
ant idea(See this for details) - Netbeans -
ant netbeans(See this for details)
Running Tests
The standard test suite can be run with the command:
ant test
Like Solr itself, the test-running can be customized or tailored in a number or ways. For an exhaustive discussion of the options available, run:
ant test-help
