> [~andrew.wang] recently had a comment on HDFS-10899:
> {quote}
> Looks like we aren't using the op cache in FSEditLog SetXAttrOp / RemoveXAttrOp. I think
this is accidental, could you do some research? Particularly since we'll be doing a lot of
SetXAttrOps, avoiding all that object allocation would be nice. This could be a separate JIRA.
> {quote}
> i.e. 
> {code}
>     static SetXAttrOp getInstance() {
>       return new SetXAttrOp();
>     }
> {code}
> v.s.
> {code}
>     static AddOp getInstance(OpInstanceCache cache) {
>       return (AddOp) cache.get(OP_ADD);
>     }
> {code}
> Seems we should fix these non-caching usages.
