Subject [jira] [Commented] (SOLR-9515) Update to Hadoop 3
Date Wed, 30 Jan 2019 18:40:00 GMT


Kevin Risden commented on SOLR-9515:

The precommit failures from above for Hadoop are real but they are an issue with commons-lang3.
I just sent a message to the commons-lang3 mailing list. I have seen these errors sporadically
as well. The stacktrace that is similar is:
ava.lang.ArrayIndexOutOfBoundsException: 4
   [junit4]   2> 	at org.apache.commons.lang3.time.FastDatePrinter$TextField.appendTo(
   [junit4]   2> 	at org.apache.commons.lang3.time.FastDatePrinter.applyRules(

   [junit4]   2> 	at [?:1.8.0_191]
This happens when the locale is set. I haven't nailed down which locales all fail but a simple
reproducing test case without Hadoop or Lucene/Solr is here:
long timestamp = System.currentTimeMillis();
 This is with commons-lang3 3.8.1 the latest release.
