Subject [jira] [Updated] (SPARK-17850) HadoopRDD should not swallow EOFException
Date Mon, 10 Oct 2016 07:27:20 GMT

     [ https://issues.apache.org/jira/browse/SPARK-17850?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Shixiong Zhu updated SPARK-17850:
---------------------------------
    Description: 
The code in https://github.com/apache/spark/blob/2bcd5d5ce3eaf0eb1600a12a2b55ddb40927533b/core/src/main/scala/org/apache/spark/rdd/HadoopRDD.scala#L256
catches EOFException and mark RecordReader finished. However, in some cases, RecordReader
will throw EOFException to indicate the stream is corrupted. See the following stack trace
as an example:
