Subject [jira] Commented: (HADOOP-1375) a simple parser for hbase.
Date Fri, 18 May 2007 18:06:16 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-1375?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12496984
] 

Doug Cutting commented on HADOOP-1375:
--------------------------------------

Lucene, Nutch & Hadoop already use JavaCC, so it's accepted.  It's not pretty, but usually
better than writing a parser from scratch.  Historically, JavaCC's license prohibited distributing
it from Apache, so we established the convention of committing its output so that not all
developers were forced to manually install it.  JavaCC is now under a BSD license, but that
convention remains.
