Virgil Palanciuc commented on SPARK-17594: ------------------------------------------ It's not - initially my example was about the ArrayOutOfBounds exception, which you're right, had already been reported. But I got that exception when trying to reproduce this issue, and now I actually reproduced it: the issue is wrong results with left-join, that didn't occur with spark 1.6, and doesn't occur if I use "<=>" instead of "===" for join. I'll try with master and let you know if it works. > Bug in left-outer join > ---------------------- > > Key: SPARK-17594 > URL: https://issues.apache.org/jira/browse/SPARK-17594 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 2.0.0 > Reporter: Virgil Palanciuc > > I have a bug where I think a left-join returns wrong results, by mistakenly > matching long values that are identical on 32bits (differ in their upper > halves). > Instructions to reproduce > {code} > scala> val x = Seq((100L,17179869185L), (102L,17179869185L), > (101L,17179869186L), (200L,17179869186L), (401L,1L), (500L,1L), > (600L,8589934593L), (700L,8589934593L), (800L,8589934593L), > (900L,8589934594L), (1000L,8589934594L), (1200L,2L), (1300L,2L), (1301L,2L), > (1400L,17179869187L), (1500L,17179869188L), > (1600L,8589934595L)).toDF("u","x1") > x: org.apache.spark.sql.DataFrame = [u: bigint, x1: bigint] > scala> val y = Seq((17179869187L,-8589934595L), (17179869188L,-8589934595L), > (17179869185L,-8589934593L)).toDF("x2","y") > y: org.apache.spark.sql.DataFrame = [x2: bigint, y: bigint] > scala> x.join(y,'x1 === 'x2, "left_outer").show() > {code} > | u| x1| x2| y| > | 100|17179869185|17179869185|-8589934593| > | 102|17179869185|17179869185|-8589934593| > | 101|17179869186| null| null| > | 200|17179869186| null| null| > | 401| 1|17179869185|-8589934593| > | 500| 1|17179869185|-8589934593| > | 600| 8589934593|17179869185|-8589934593| > | 700| 8589934593|17179869185|-8589934593| > | 800| 8589934593|17179869185|-8589934593| > | 900| 8589934594| null| null| > |1000| 8589934594| null| null| > |1200| 2| null| null| > |1300| 2| null| null| > |1301| 2| null| null| > |1400|17179869187|17179869187|-8589934595| > |1500|17179869188|17179869188|-8589934595| > |1600| 8589934595|17179869187|-8589934595| -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
