Summary: Improvements to ColumnVector
Key: SPARK-14448
URL: https://issues.apache.org/jira/browse/SPARK-14448
Project: Spark
Issue Type: Improvement
Components: SQL
Reporter: Ted Yu
Priority: Minor
In this issue, two changes are proposed for ColumnVector :
1. ColumnVector should be declared as implementing AutoCloseable - it already
has close() method
2. In OnHeapColumnVector#reserveInternal(), we only need to allocate new array
when existing array is null or the length of existing array is shorter than the
newCapacity.
