---------------------------------------
Summary: Add a ozoneFilesystem related api's to OzoneManager to
reduce redundant lookups
Key: HDDS-1112
URL: https://issues.apache.org/jira/browse/HDDS-1112
Project: Hadoop Distributed Data Store
Issue Type: Bug
Components: Ozone Filesystem
Affects Versions: 0.4.0
Reporter: Mukul Kumar Singh
Assignee: Mukul Kumar Singh
Fix For: 0.4.0
With the current OzoneFilesystem design, most of the lookups while create
happens via that getFileStatus api, which inturn does a getKey or a list Key
for the keys in the Ozone bucket.
In most of the cases, the files do not exists before creation, and hence these
lookups corresponds to wasted time in lookup. This jira proposes to optimize
the "create" and "getFileState" api in OzoneFileSystem by introducing
OzoneFilesystem friendly apis in OM.
