Cameron Todd commented on SPARK-18105:
--------------------------------------
Yep I understand. I have attached my hashed data keeping the same distribution
and the full_name hashed column is weak but string distance functions still
work on it. So this line of code:
{code:java}
Dataset<Row> relevantPivots = spark.read().parquet(pathToDataDedup)
.select("id", "full_name",
"last_name","birthdate")
.na().drop()
.withColumn("pivot_hash",
hash(col("last_name"),col("birthdate")))
.drop("last_name","birthdate")
.repartition(5000)
.cache();
// can be replaced with this
Dataset<Row> relevantPivots =
spark.read().parquet(pathToDataDedup).repartition(5000).cache();{code}
I have also run the same code on the same hashed data and getting the same
corrupted stream error. Also in case it wasn't clear my data normally sits on
an s3 bucket.
