Sean Owen resolved SPARK-5357. ------------------------------ Resolution: Fixed Fix Version/s: 1.3.0 Issue resolved by pull request 4153 [https://github.com/apache/spark/pull/4153] > Upgrade from commons-codec 1.5 > ------------------------------ > > Key: SPARK-5357 > URL: https://issues.apache.org/jira/browse/SPARK-5357 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 1.1.0, 1.2.0 > Reporter: Matthew Whelan > Fix For: 1.3.0 > > Original Estimate: 24h > Remaining Estimate: 24h > > Spark uses commons-codec 1.5, which has a race condition in Base64. That > race was introduced in commons-codec 1.4 and resolved in 1.7. The current > version of commons-codec is 1.10. > Code that runs in Workers and assumes that Base64 is thread-safe will break > because spark is using a non-thread-safe version. See CODEC-96 > In addition, the spark.files.userClassPathFirst mechanism is currently > broken, (bug to come), so there isn't a viable work around for this issue. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
