Subject [jira] [Commented] (SPARK-5594) SparkException: Failed to get broadcast (TorrentBroadcast)
Date Wed, 18 Oct 2017 07:46:00 GMT

    [ https://issues.apache.org/jira/browse/SPARK-5594?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16208936#comment-16208936
] 

Hristo Angelov commented on SPARK-5594:
---------------------------------------

[~hryhoriev.nick] I have exactly the same problem. The application is working fine(in my case
for 4-5 days) and then this exception occurs. The strange thing is that my broadcast variable
is with index 0:

{code:java}
INFO TorrentBroadcast: Started reading broadcast variable 0
{code}

So this broadcast variable is only read when the exception occurred and never before that.
I'm using spark version 2.2.0. So did you find out what lead to that error?

> I am uncertain whether this is a bug, however I am getting the error below when running
on a cluster (works locally), and have no idea what is causing it, or where to look for more
information.
> Any help is appreciated.  Others appear to experience the same issue, but I have not
found any solutions online.
> Please note that this only happens with certain code and is repeatable, all my other
spark jobs work fine.
