Distributed Release Audit Tool (DRAT)

A distributed, parallelized (Map Reduce) wrapper around Apache™ RAT to allow it to complete on large code repositories of multiple file types where Apache™ RAT hangs forever.

The tool leverages Apache™ OODT to parllelize ane workflow together the following components:

  1. Apache™ SOLR based exploration of a CM repository (e.g., Git, SVN, etc.) and classification of that repository based on MIME type using Apache™ Tika.
  2. A MIME partitioner that uses Apache™ Tika to automatically deduce and classify by file type and then partition Apache™ RAT jobs based on sets of 100 files per type (configurable) -- the M/R “partitioner”
  3. A throttle wrapper for RAT to MIME targeted Apache™ RAT. -- the M/R “mapper”
  4. A reducer to “combine” the produced RAT logs together into a global RAT report that can be used for stats generation. -- the M/R “reducer”

How to Build

You can build DRAT in a few steps:

  1. mkdir -p /usr/local/drat/deploy
  2. mkdir -p /usr/local/drat/src
  3. cd /usr/local/drat/
  4. git clone https://github.com/chrismattmann/drat.git
  5. mv drat src && cd src
  6. mvn install
  7. cp -R target/distribution/dms-distribution-0.1-bin.tar.gz deploy
  8. cd deploy
  9. tar xvzf dms-distribution-0.1-bin.tar.gz
  10. rm -rf *.tar.gz

How to Run

Here are the basic commands to run DRAT. Imagine you had a code repo, your-repo, that lives in $HOME/your-repo.

  1. Set your $DRAT_HOME environment variable, e.g., to /usr/local/drat/deploy

  2. Start Apache™ OODT
    cd $DRAT_HOME
    cd filemgr/bin && ./filemgr start
    cd ../../workflowbin/ && ./wmgr start

  3. Crawl the repository of interest, e.g., $HOME/your-repo:
    cd $DRAT_HOME/crawler/bin
    ./crawler_launcher --operation --metPC --productPath $HOME/your-repo --metExtractorConfig $DRAT_HOME/extractors/code/default.cpr.conf --metExtractor org.apache.oodt.cas.metadata.extractors.CopyAndRewriteExtractor --filemgrUrl http://localhost:9000 --clientTransferer org.apache.oodt.cas.filemgr.datatransfer.InPlaceDataTransferFactory

  4. Index the crawled repo in Apache™ SOLR:
    cd $DRAT_HOME/filemgr/bin
    java -Djava.ext.dirs=../lib -DSOLR_INDEXER_CONFIG=../etc/indexer.properties org.apache.oodt.cas.filemgr.tools.SolrIndexer --all --fmUrl http://localhost:9000 --optimize --solrUrl http://localhost:8080/solr/drat

  5. Fire off the partitioner and mappers
    cd $DRAT_HOME/workflow/bin
    ./wmgr-client --url http://localhost:9001 --operation --dynWorkflow --taskIds urn:drat:MimePartitioner

  6. Fire off the reducer
    cd $DRAT_HOME/workflow/bin
    ./wmgr-client --url http://localhost:9001 --operation --dynWorkflow --taskIds urn:drat:RatAggregator
