[jira] [Created] (SPARK-16613) A bug in RDD pipe operation
Alex Krasnyansky created SPARK-16613:
----------------------------------------
Summary: A bug in RDD pipe operation
Key: SPARK-16613
URL: https://issues.apache.org/jira/browse/SPARK-16613
Project: Spark
Issue Type: Bug
Reporter: Alex Krasnyansky
Suppose we have such Spark code
{code}
object PipeExample {
def main(args: Array[String]) {
val fstRdd = sc.parallelize(List("hi", "hello", "how", "are", "you"))
val pipeRdd = fstRdd.pipe("/Users/finkel/spark-pipe-example/src/main/resources/len.sh")
pipeRdd.collect.foreach(println)
}
}
{code}
It uses a bash script to convert a string to its length.
{code}
#!/bin/sh
read input
len=${#input}
echo $len
{code}
So far so good, but when I run the code, it prints incorrect output. For example:
{code}
0
2
0
5
3
0
3
3
{code}
I expect to see
{code}
2
5
3
3
3
{code}
which it correct output for the app. I think it's a bug. It's expected to see only positive integers and avoid zeros.
