> This is a continuation of HADOOP-17901.
> Right now we use a factor of 1.5x to increase the byte array if it's full.
> However, if the size reaches a certain point, the increment is only (current
> size + length). This can cause performance issues if the textual data which
> we intend to store is beyond this point.
> Instead, let's max out the array to the maximum. Based on different sources,
> a safe choice seems to be Integer.MAX_VALUE - 8 (see ArrayList,
> AbstractCollection, HashTable, etc).
