Kapil Singh created SPARK-16890: ----------------------------------- Summary: substring returns wrong result for positive position Key: SPARK-16890 URL: https://issues.apache.org/jira/browse/SPARK-16890 Project: Spark Issue Type: Bug Components: SQL Affects Versions: 2.0.0, 1.6.2, 1.5.2 Reporter: Kapil Singh
If position > 0 then substring function reduces it by 1. So if it is invoked like substring("First", 1, 4) then result is "Fir" instead of "irs". This is because UTF8String's substring method does this fancy modification before invoking substring on underlying String. -- 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
