Hi David,

You can try "cat" command and copy the file to local filesystem and view it[1]. But it seems you need to view it directly within hdfs. i'm not sure if there's any hadoop commands to get it done, but i have read/write to hdfs using small java applets. It's well documented in following links [2] [3] . Hope it helps.

Hello,

Is there a way to view files in the Hadoop HDFS?  I have a directory of files like this:
[cloudera@quickstart ~]$ hdfs dfs -ls  /user/hive/warehouse/categories
 
Found 2 items
-rw-r--r--   1 cloudera hive          0 2014-11-05 13:18 /user/hive/warehouse/categories/_SUCCESS
-rw-r--r--   1 cloudera hive       1344 2014-11-05 13:18 /user/hive/warehouse/categories/part-m-00000.avro
[cloudera@quickstart ~]$ 
[cloudera@quickstart ~]$ 
I imported a table using Sqoop.

I tried the following commands but they are not working:
