---------------------------------------
Summary: Race conditions caused by
org.apache.hadoop.conf.Configuration: error parsing conf
java.io.BufferedInputStream
Key: HADOOP-15331
URL: https://issues.apache.org/jira/browse/HADOOP-15331
Project: Hadoop Common
Issue Type: Bug
Components: common
Affects Versions: 3.0.0, 2.7.5, 2.8.3, 2.9.0, 3.1.0, 2.10.0
Reporter: Miklos Szegedi
Assignee: Miklos Szegedi
There is a race condition in the way Hadoop handles the Configuration class.
The scenario is the following. Let's assume that there are two threads sharing
the same Configuration class. One adds some resources to the configuration,
while the other one clones it. Resources are loaded lazily in a deferred call
to {{loadResources()}}. If the cloning happens after adding the resources but
before parsing them, some temporary resources like input stream pointers are
cloned. Eventually both copies will load the input stream resources pointing to
the same input streams. One parses the input stream XML and closes it updating
it's own copy of the resource. The other one has another pointer to the same
input stream. When it tries to load it, it will crash with a stream closed
exception.
Here is an example unit test:
{code:java}
@Test
public void testResourceRace() throws Exception {
InputStream is = new InputStream() {
InputStream is =
new ByteArrayInputStream(
"<configuration></configuration>".getBytes());
@Override
public int read() throws IOException {
return is.read();
}
};
Configuration conf = new Configuration();
conf.addResource(new BufferedInputStream(is));
Configuration confClone = new Configuration(conf);
confClone.get("firstParse");
conf.get("secondParse");
}{code}
