----------------------------------------
Summary: Implement getReadCopy in Table.
Key: HDDS-3623
URL: https://issues.apache.org/jira/browse/HDDS-3623
Project: Hadoop Distributed Data Store
Issue Type: Bug
Reporter: Bharat Viswanadham
Assignee: Bharat Viswanadham
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 like
https://issues.apache.org/jira/browse/HDDS-2344. To avoid this, all the get()
values returned are cloned copy if it exists in cache.
But for 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.
