Subject [jira] [Updated] (HADOOP-9565) Add a Blobstore interface to add to blobstore FileSystems
Date Sat, 13 Feb 2016 15:13:18 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-9565?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Thomas Demoor updated HADOOP-9565:
----------------------------------
    Attachment: HADOOP-9565-005.patch

Adjusted distcp: removed tempfile usage for object stores that support direct concurrent writes.
Evidently, this yields a 2x speedup . 

AFAIK we have most things covered now?

> We can make the fact that some {{FileSystem}} implementations are really blobstores,
with different atomicity and consistency guarantees, by adding a {{Blobstore}} interface to
add to them. 
> This could also be a place to add a {{Copy(Path,Path)}} method, assuming that all blobstores
implement at server-side copy operation as a substitute for rename.
