Subject [jira] [Commented] (CONNECTORS-1219) Lucene Output Connector
Date Mon, 03 Aug 2015 00:42:04 GMT

    [ https://issues.apache.org/jira/browse/CONNECTORS-1219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14651313#comment-14651313

Shinichiro Abe commented on CONNECTORS-1219:
--------------------------------------------

currently I took a solrcloud on hdfs way where the relationship between an indexwriter and
an index directory is 1 by 1. In HdfsDirectory, I can replace HdfsLockFactory with NoLockFactory
which OakDirectory applies. If I do, perhaps multiple indexwriters will happen some errors
about when updating an index segment because each indexwriter has each segment info, when
updating index segment, then an indexwriter realizes the difference between a segment info
itself and an existing segment info which other' writer wrote, as a result some exception
will throw. It is worth to try to change NoLockFactory for me, but I think this impl is risky
thouth, I'll look into this next weekend. Thanks.

> A output connector for Lucene local index directly, not via remote search engine. It
would be nice if we could use Lucene various API to the index directly, even though we could
do the same thing to the Solr or Elasticsearch index. I assume we can do something to classification,
categorization, and tagging, using e.g lucene-classification package.
