Subject [jira] [Created] (HADOOP-9740) FsShell's Text command does not read avro data files stored on HDFS

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

             Summary: FsShell's Text command does not read avro data files stored on HDFS
                 Key: HADOOP-9740
                 URL: https://issues.apache.org/jira/browse/HADOOP-9740
             Project: Hadoop Common
          Issue Type: Bug
          Components: fs
    Affects Versions: 2.0.5-alpha
            Reporter: Allan Yan


HADOOP-8597 added support for reading avro data files from FsShell Text command. However,
it does not work with files stored on HDFS. Here is the error message:
{code}
$hadoop fs -text hdfs://localhost:8020/test.avro
-text: URI scheme is not "file"
Usage: hadoop fs [generic options] -text [-ignoreCrc] <src> ...
{code}

The problem is because the File constructor complains not able to recognize hdfs:// scheme
in during AvroFileInputStream initialization. 

There is a unit TestTextCommand.java under hadoop-common project. However it only tested files
in local file system. I created a similar one under hadoop-hdfs project using MiniDFSCluster.
Please see attached maven unit test error message with full stack trace for more details.
