Subject [jira] [Created] (CASSANDRA-5587) BulkLoader fails with NoSuchElementException
Date Wed, 22 May 2013 05:51:20 GMT
Julien Aymé created CASSANDRA-5587:
--------------------------------------

             Summary: BulkLoader fails with NoSuchElementException
                 Key: CASSANDRA-5587
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5587
             Project: Cassandra
          Issue Type: Bug
          Components: Tools
    Affects Versions: 1.2.5, 1.2.4
            Reporter: Julien Aymé


When using BulkLoader tool (sstableloader command) to transfer data from a cluster to another,

a java.util.NoSuchElementException is thrown whenever the directory contains a "snapshot"
sub directory,
and the bulk load fails.

The fix should be quite simple:
Catch any NoSuchElementException thrown in {{SSTableLoader#openSSTables()}}

The directory structure:
