Liang-Chi Hsieh created SPARK-15430: ---------------------------------------
Summary: Access ListAccumulator's value could possibly cause java.util.ConcurrentModificationException Key: SPARK-15430 URL: https://issues.apache.org/jira/browse/SPARK-15430 Project: Spark Issue Type: Bug Components: SQL Reporter: Liang-Chi Hsieh In ListAccumulator we create an unmodifiable view for underlying list. However, it doesn't prevent the underlying to be modified further. So as we access the unmodifiable list, the underlying list can be modified in the same time. It could cause java.util.ConcurrentModificationException. We should fix it. -- 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
