org.apache.hadoop.hive.ql.exec.vector.BytesColumnVector

This class supports string and binary data by value reference -- i.e. each field is explicitly present, as opposed to provided by a dictionary reference. In some cases, all the values will be in the same byte array to begin with, but this need not be the case. If each value is in a separate byte array to start with, or not all of the values are in the same original byte array, you can still assign data by reference into this column vector. This gives flexibility to use this in multiple situations.

When setting data by reference, the caller is responsible for allocating the byte arrays used to hold the data. You can also set data by value, as long as you call the initBuffer() method first. You can mix "by value" and "by reference" in the same column vector, though that use is probably not typical.
