--------------------------------------
[~zhz] , your patch is missing start thread. It worked when I overrided method
"openForWrite"
class FSEditLogAsync extends FSEditLog implements Runnable {
......
_@Override_
void openForWrite(int layoutVersion) throws IOException {
try {
startSyncThread();
super.openForWrite(layoutVersion);
} catch (IOException ioe) {
stopSyncThread();
throw ioe;
}
}
......
