> My Cluster hang yesterday .
> Becuase the rpc server Reader threads crash. So all rpc request timeout,
> include datanode hearbeat &.
> We can see , the method doRunLoop just catch InterruptedException and
> IOException:
> while (running) {
> SelectionKey key = null;
> try {
> // consume as many connections as currently queued to avoid
> // unbridled acceptance of connections that starves the select
> int size = pendingConnections.size();
> for (int i=size; i>0; i--) {
> Connection conn = pendingConnections.take();
> conn.channel.register(readSelector, SelectionKey.OP_READ, conn);
> }
> readSelector.select();
> Iterator<SelectionKey> iter =
> readSelector.selectedKeys().iterator();
> while (iter.hasNext()) {
> key = iter.next();
> iter.remove();
> if (key.isValid()) {
> if (key.isReadable()) {
> doRead(key);
> }
> }
> key = null;
> }
> } catch (InterruptedException e) {
> if (running) { // unexpected -- log it
> LOG.info(Thread.currentThread().getName() + " unexpectedly
> interrupted", e);
> }
> } catch (IOException ex) {
> LOG.error("Error in Reader", ex);
> }
> }
