John Doe created HDFS-14481:
-------------------------------
Summary: BenchmarkThroughput.writeLocalFile hangs with
misconfigured BUFFER_SIZE
Key: HDFS-14481
URL: https://issues.apache.org/jira/browse/HDFS-14481
Project: Hadoop HDFS
Issue Type: Bug
Components: test
Affects Versions: 2.5.0
Reporter: John Doe
When the configuration file is corrupted, reading BUFFER_SIZE from corrupted
conf can return 0.
The "for" loop in BenchmarkThroughput.writeLocalFile function hangs endlessly.
Here is the code snippet.
{code:java}
BUFFER_SIZE = conf.getInt("dfsthroughput.buffer.size", 4 * 1024);
private Path writeLocalFile(String name, Configuration conf,
long total) throws IOException {
Path path = dir.getLocalPathForWrite(name, total, conf);
System.out.print("Writing " + name);
resetMeasurements();
OutputStream out = new FileOutputStream(new File(path.toString()));
byte[] data = new byte[BUFFER_SIZE];
for(long size=0; size < total; size += BUFFER_SIZE) {//Bug!!!
System.out.println("inside for loop...size = " + size);
out.write(data);
}
out.close();
printMeasurements();
return path;
}
{code}
This configuration error also affects HDFS-13513, HDFS-13514
