[jira] [Commented] (SOLR-9079) Upgrade commons-lang to version 3.x

    [ https://issues.apache.org/jira/browse/SOLR-9079?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16759112#comment-16759112 ] 

Kevin Risden commented on SOLR-9079:
------------------------------------

Would be good to look at this again on master/8.x since SOLR-9515 upgraded Hadoop to Hadoop 3. There has been a lot of improvements on the Hadoop 3.x side in regards to dependency versions.

> Current version used is [/commons-lang/commons-lang = 2.6|https://github.com/apache/lucene-solr/blob/master/lucene/ivy-versions.properties#L68] and a key motivation would be to have [commons.lang3|http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/package-summary.html] APIs available e.g. [org.apache.commons.lang3.tuple.Pair|http://commons.apache.org/proper/commons-lang/apidocs/index.html?org/apache/commons/lang3/tuple/Pair.html] as an alternative to [org.apache.solr.common.util.Pair|https://github.com/apache/lucene-solr/blob/master/solr/solrj/src/java/org/apache/solr/common/util/Pair.java] variant.

> So upgrading commons-lang can't happen anytime soon but this ticket here to track motivations and findings so far for future reference.
