Pete Robbins created SPARK-12470: ------------------------------------ Summary: Incorrect calculation of row size in o.a.s.catalyst.expressions.codegen.GenerateUnsafeRowJoiner Key: SPARK-12470 URL: https://issues.apache.org/jira/browse/SPARK-12470 Project: Spark Issue Type: Bug Affects Versions: 1.5.2 Reporter: Pete Robbins Priority: Minor
While looking into https://issues.apache.org/jira/browse/SPARK-12319 I noticed that the row size is incorrectly calculated. The "sizeReduction" value is calculated in words: // The number of words we can reduce when we concat two rows together. // The only reduction comes from merging the bitset portion of the two rows, saving 1 word. val sizeReduction = bitset1Words + bitset2Words - outputBitsetWords but then it is subtracted from the size of the row in bytes: | out.pointTo(buf, ${schema1.size + schema2.size}, sizeInBytes - $sizeReduction); -- 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
