[jira] [Created] (HIVE-21431) Vectorization: ltrim throws ArrayIndexOutOfBounds in corner cases

Rajesh Balamohan created HIVE-21431:
---------------------------------------

             Summary: Vectorization: ltrim throws ArrayIndexOutOfBounds in corner cases
                 Key: HIVE-21431
                 URL: https://issues.apache.org/jira/browse/HIVE-21431
             Project: Hive
          Issue Type: Bug
          Components: Vectorization
    Affects Versions: 2.3.4
            Reporter: Rajesh Balamohan


In corner cases, {{ltrim}} with string columns throws arraryindexoutofboundsexception with vectorization enabled. {{HIVE-19565}} seem to fix corner cases.  But in another corner case, {{length[]}} was all {{0}} and this causes {{-1}} to be returned in the length to be set in the target vector. I will check if i can get a easier repro for this.
