[jira] [Created] (HDFS-13209) DistributedFileSystem.create should allow an option to provide StoragePolicy

Jean-Marc Spaggiari created HDFS-13209:
------------------------------------------

             Summary: DistributedFileSystem.create should allow an option to provide StoragePolicy
                 Key: HDFS-13209
                 URL: https://issues.apache.org/jira/browse/HDFS-13209
             Project: Hadoop HDFS
          Issue Type: New Feature
          Components: hdfs
    Affects Versions: 3.0.0
            Reporter: Jean-Marc Spaggiari


DistributedFileSystem.create allows to get a FSDataOutputStream. The stored file and related blocks will used the directory based StoragePolicy.

 

However, sometime, we might need to keep all files in the same directory (consistency constraint) but might want some of them on SSD (small, in my case) until they are processed and merger/removed. Then they will go on the default policy.

 

When creating a file, it will be useful to have an option to specify a different StoragePolicy...
