-------------------------------------
Summary: Modify Text.ensureCapacity() to efficiently max out the
backing array size
Key: HADOOP-17905
URL: https://issues.apache.org/jira/browse/HADOOP-17905
Project: Hadoop Common
Issue Type: Improvement
Reporter: Peter Bacsko
Assignee: Peter Bacsko
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,
this is usually determined to be Integer.MAX_VALUE - 8 (see ArrayList,
AbstractCollection, HashTable, etc).
