Subject [jira] [Commented] (SPARK-11170) ​ EOFException on History server reading in progress lz4
Date Sat, 17 Oct 2015 22:53:05 GMT

    [ https://issues.apache.org/jira/browse/SPARK-11170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14962107#comment-14962107
] 

Sebastian YEPES FERNANDEZ commented on SPARK-11170:
---------------------------------------------------

I also tried 'spark.eventLog.compress = false' as a workaround, but it was still saving the
file with the IO codec.
