BELUGA BEHR created HADOOP-15962:
------------------------------------
Summary: FileUtils Small Buffer Size
Key: HADOOP-15962
URL: https://issues.apache.org/jira/browse/HADOOP-15962
Project: Hadoop Common
Issue Type: Improvement
Components: common
Affects Versions: 3.3.0
Reporter: BELUGA BEHR
Note sure if this code is even being used, but it implements a copy routing
utilizing a 2K buffer. Modern JVM uses 8K, but 4K should be minimum. Also,
there are libraries for this stuff.
{code:java|title=FileUtil.java}
int count;
byte data[] = new byte[2048];
try (BufferedOutputStream outputStream = new BufferedOutputStream(
new FileOutputStream(outputFile));) {
while ((count = tis.read(data)) != -1) {
outputStream.write(data, 0, count);
}
outputStream.flush();
}
{code}
I also fixed a couple of check-style warnings.
