> Use faster function to point to instead of copy immutable byte arrays

> Key: HIVE-21313
> URL: https://issues.apache.org/jira/browse/HIVE-21313
> Project: Hive
> Issue Type: Improvement
> Affects Versions: All Versions
> Reporter: ZhangXin
> Assignee: ZhangXin
> Priority: Minor
> Labels: pull-request-available
> Fix For: All Versions
>
> Attachments: HIVE-21313.patch, HIVE-21313.patch
>
> Time Spent: 10m
> Remaining Estimate: 0h
>
> In file ql/src/java/org/apache/hadoop/hive/ql/exec/vector/VectorAssignRow.java
> We may find code like this:
> ```
> Text text = (Text) convertTargetWritable;
> if (text == null)
> { text = new Text(); }
> text.set(string);
> ((BytesColumnVector) columnVector).setVal(
> batchIndex, text.getBytes(), 0, text.getLength());
> ```
>
> Using `setVal` method can copy the bytes array generated by
> `text.getBytes()`. This is totally unnecessary at all. Since the bytes array
> is immutable, we can just use `setRef` method to point to the specific byte
> array, which will also lower the memory usage.
