> Project: Hadoop Distributed Data Store

>
> Introduce a getReadCopy in table method.
> As right now, get when a value exists in the cache it returns the cloned
> copy, so that when it used during double-buffer flush, if other threads
> modify the object during the flush time we will see some exceptions which are
> mentioned in HDDS-2344 and HDDS-2322. To avoid this, all the get() values
> returned are cloned copy if it exists in the cache.
> But for a few of the requests like OMBucketCreateRequest, we need Volume info
> (OmVolumeArgs, but we don't use this info during double buffer flush, so we
> can safely get a cached copy without doing a clone. In this Jira, fixed only
> Bucket requests. I Will file a new Jira to see where all this new API can be
> safely used.
