File cache loader in a cluster was failing with EOF exception while
restoring an object, under load. It looks like the original hash map was not
getting written properly. The original code is given below:
protected void storeAttributes(Fqn fqn, Map attrs) throws Exception
{
File f = getDirectory(fqn, true);
File child = new File(f, DATA);
if (!child.exists())
if (!child.createNewFile())
throw new IOException("Unable to create file: " + child);
FileOutputStream out = new FileOutputStream(child);
ObjectOutputStream output = new ObjectOutputStream(out);
output.writeObject(attrs);
out.close();
}
Changing the code as given below seems to fix the issue.
protected void storeAttributes(Fqn fqn, Map attrs) throws Exception
{
File f = getDirectory(fqn, true);
File child = new File(f, DATA);
if (!child.exists())
if (!child.createNewFile())
throw new IOException("Unable to create file: " + child);
FileOutputStream out = new FileOutputStream(child);
try
{
MarshalledValueOutputStream output =
new MarshalledValueOutputStream(out);
output.writeObject(attrs);
output.close();
out = null;
}
finally
{
if(out != null)
out.close();
}
}
