Subject [jira] [Commented] (HDFS-5343) When cat command is issued on snapshot files getting unexpected result
Date Fri, 24 Jan 2014 09:34:41 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5343?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13880849#comment-13880849

Uma Maheswara Rao G commented on HDFS-5343:

Thanks for the update.
Taking from my previous comment:
try {
+        ToolRunner.run(conf, shell, new String[] { "-cat",
+            "/TestSnapshotFileLength/sub1/.snapshot/snapshot1/file1" });
+    } catch (Exception e) {
+        e.printStackTrace();
+    }
I think you need not catch exception here right?

Could you please answer above question?

> first if we create one file with some file length and take the snapshot of that file,and
again append some data through append method to that file,then if we do cat command operation
on snapshot of that file,in general it should dispaly the data what we added with create operation,but
it is displaying the total data i.e. create +_ appended data.
> but if we do the same operation and if we read the contents of snapshot file through
input stream it is just displaying the data created in snapshoted files.
> in this the behaviour of cat command and reading through inputstream is getting different
