             Summary: Text shell command unnecessarily demands that a SequenceFile's key class
be WritableComparable
                 Key: HADOOP-8395
                 URL: https://issues.apache.org/jira/browse/HADOOP-8395
             Project: Hadoop Common
          Issue Type: Bug
          Components: util
    Affects Versions: 2.0.0
            Reporter: Harsh J
            Priority: Trivial


Text from Display set of Shell commands (hadoop fs -text), has a strict subclass check for
a sequence-file-header loaded key class to be a subclass of WritableComparable.

The sequence file writer itself has no such checks (one can create sequence files with just
plain writable keys, comparable is needed for sequence file's sorter alone, which not all
of them use always), and hence its not reasonable for Text command to carry it either.

We should relax the check and simply just check for "Writable", not "WritableComparable".
