Xiangrui Meng commented on SPARK-3828:
--------------------------------------
`text8` doesn't contain any line feed character. So the number of records
depend on the max char per line setting.
> Spark returns inconsistent results when building with different Hadoop
> version

>
> Key: SPARK-3828
> URL: https://issues.apache.org/jira/browse/SPARK-3828
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.1.0
> Environment: OSX 10.9, Spark master branch
> Reporter: Liquan Pei
>
> For text8 data at http://mattmahoney.net/dc/text8.zip. To reproduce, please
> unzip first.
> Spark build with different Hadoop version returns different result.
> {code}
> val data = sc.textFile("text8")
> data.count()
> {code}
> returns 1 when built with SPARK_HADOOP_VERSION=1.0.4 and return 2 when built
> with SPARK_HADOOP_VERSION=2.4.0.
> Looking through the rdd code, it seems that textFile uses hadoopFile which
> creates HadoopRDD, we should probably create newHadoopRDD when building spark
> with SPARK_HADOOP_VERSION >= 2.0.0.
