[jira] [Commented] (SPARK-4978) Core dump when running any example
with prebuilt Hadoop 2.4 binaries
[ https://issues.apache.org/jira/browse/SPARK-4978?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14259599#comment-14259599 ]
Sean Owen commented on SPARK-4978:
----------------------------------
In general this is evidence of an OpenJDK bug, as the message suggests. Java programs can't themselves crash like this. An exception may be those that call native code. Spark does not. Hadoop does in some cases. But there is nothing here suggesting a connection to native or Hadoop code. I think this appears unrelated to Spark.
