> If a processor chain is used with custom processors, 
> they are not used in case of node failure during log replay.
> Here is the code:
> {code:title=UpdateLog.java|borderStyle=solid}
>     public void doReplay(TransactionLog translog) {
>       try {
>         loglog.warn("Starting log replay " + translog + " active="+activeLog + " starting
pos=" + recoveryInfo.positionOfStart);
>         tlogReader = translog.getReader(recoveryInfo.positionOfStart);
>         // NOTE: we don't currently handle a core reload during recovery.  This would
cause the core
>         // to change underneath us.
>         // TODO: use the standard request factory?  We won't get any custom configuration
instantiating this way.
>         RunUpdateProcessorFactory runFac = new RunUpdateProcessorFactory();
>         DistributedUpdateProcessorFactory magicFac = new DistributedUpdateProcessorFactory();
>         runFac.init(new NamedList());
>         magicFac.init(new NamedList());
>         UpdateRequestProcessor proc = magicFac.getInstance(req, rsp, runFac.getInstance(req,
rsp, null));
> {code} 
> I think this is a big issue, because a lot of people will discover it when a node will
crash in the best case... and I think it's too late.
> It means to me that processor chains are not usable with Solr Cloud currently.
