-----------------------------

             Summary: When cat command is issued on snapshot files getting 
unexpected result
                 Key: HDFS-5343
                 URL: https://issues.apache.org/jira/browse/HDFS-5343
             Project: Hadoop HDFS
          Issue Type: Bug
          Components: hdfs-client
            Reporter: sathish


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
