[jira] [Commented] (SPARK-5770) Use addJar() to upload a new jar file to executor, it can't be added to classloader

    [ https://issues.apache.org/jira/browse/SPARK-5770?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15347750#comment-15347750 ] 

huangning commented on SPARK-5770:
----------------------------------

Because it is not support deleteJar or updataJar, so I can't update class without restart thrift server

> First use addJar() to upload a jar to the executor, then change the jar content and upload it again. We can see the jar file in the local has be updated, but the classloader still load the old one. The executor log has no error or exception to point it.
> I use spark-shell to test it. And set "spark.files.overwrite" is true.
