Sven Meys created HADOOP-8853:
---------------------------------
Summary: BytesWritable setsize unchecked
Key: HADOOP-8853
URL: https://issues.apache.org/jira/browse/HADOOP-8853
Project: Hadoop Common
Issue Type: Bug
Components: io
Affects Versions: 2.0.1-alpha
Reporter: Sven Meys
When setting an array of length 1183230720 (in my case), the method will return
a negative array index exception.
Cause is the following method.
public void setSize(int size) {
if (size > getCapacity()) {
setCapacity(size * 3 / 2);
}
this.size = size;
}
size * 3 has precedence which means that for any value greater than 715.827.882
(682,6 MB) this method is unsafe.
It would be nice to have this hidden feature documented or have a failsafe in
place.
