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:

Then HadoopRDD doesn't fail the job when files are corrupted (e.g., corrupted
gzip files).
Note: NewHadoopRDD doesn't have this issue.
