Harsh J created HADOOP-8395: ------------------------------- 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". -- This message is automatically generated by JIRA.
