Subject [jira] [Created] (HDFS-11598) Improve -setrep for Erasure Coded files
Date Thu, 30 Mar 2017 17:38:41 GMT
Wei-Chiu Chuang created HDFS-11598:

             Summary: Improve -setrep for Erasure Coded files
                 Key: HDFS-11598
                 URL: https://issues.apache.org/jira/browse/HDFS-11598
             Project: Hadoop HDFS
          Issue Type: Improvement
          Components: shell
    Affects Versions: 3.0.0-alpha1
            Reporter: Wei-Chiu Chuang

Quoting my comments in HDFS-10974:

Looking at code again, I think we can improve the handling of EC files better:

* In SetReplication#processPath, can we check if the file is EC before invoking setReplication()
on it?
* -setrep also has a command switch -w to wait for the file to be replicated. Can we ignore
this if the file is erasure coded?
Also, in fact, -setrep only make sense for HDFS file system...
