Jian Chen updated SPARK-14064:
------------------------------
Description:
I have some unique keys stored as RDD[Int] , then I use zipWithIndex to give an
unique ID to every key.
val dataID = data.zipWithIndex()
Then I count the num :
dataID.count
At last, I save the dataID as textFile to HDFS.
I save the data for three times as d1, d2 ,d2, but I find each result is
different.
dataID.saveAsTextFile("d1")
dataID.saveAsTextFile("d2")
dataID.saveAsTextFile("d3")
For example
The key 13552359 has an ID 187480 in d1, but has an another ID 187483 in d2.
