Sergey Shelukhin created HDFS-7878:
--------------------------------------
Summary: API - expose an unique file identifier
Key: HDFS-7878
URL: https://issues.apache.org/jira/browse/HDFS-7878
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Sergey Shelukhin
See HDFS-487.
Even though that is resolved as duplicate, the ID is actually not exposed by
the JIRA it supposedly duplicates.
INode ID for the file should be easy to expose; alternatively ID could be
derived from block IDs, to account for appends...
This is useful e.g. for cache key by file, to make sure cache stays correct
when file is overwritten.
