Patrick Cording created SPARK-30633:
---------------------------------------
Summary: Codegen fails when xxHash seed is not an integer
Key: SPARK-30633
URL: https://issues.apache.org/jira/browse/SPARK-30633
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.4.4
Reporter: Patrick Cording
If the seed for xxHash is not an integer the generated code does not compile.
Steps to reproduce:
{code:java}
import org.apache.spark.sql.catalyst.expressions.XxHash64
import org.apache.spark.sql.Column
val file = "..."
val column = col("...")
val df = spark.read.csv(file)
def xxHash(seed: Long, cols: Column*): Column = new Column(
XxHash64(cols.map(_.expr), seed)
)
val seed = (Math.pow(2, 32)+1).toLong
df.select(xxHash(seed, column)).show()
{code}
Appending an L to the seed when the datatype is long fixes the issue.
