             Summary: NoSuchElementException using sstableloader when extra files (not Index/Data) exist under keyspace/CF of the restored folder
                 Key: CASSANDRA-5653
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5653
             Project: Cassandra
          Issue Type: Bug
          Components: Tools
         Environment: MacOs
            Reporter: Alex Zarutin


Error, I received during the "loading" data back into Cassandra using sstableloader. The content of Keyspace1/Standard1/ is what was copied in full from data/Keyspace1/Standard1/.

If Stabdard, json, etc files (except of *Index* and *Data*) are removed, problem is gone. 

According documentation, (page 191):
http://www.datastax.com/doc-source/pdf/cassandra12.pdf

where <dir_name> is the directory containing the SStables. Only the -Data and -Index components are required; -Statistics and -Filter are ignored.

It seems that extra files need to be removed in order to be "safe" during this procedure running. 

Steps to repro:
1. Create tons of the files under ..../data/Keyspace1/Standard1
2. ccm stop
3. Move content of /data/Keyspace1/Standard1 under ~/.ccm/data-1.2.6
4.
$> ./sstableloader -d 127.0.0.1  -v -debug ~/.ccm/data-1.2.6/Keyspace1/Standard1/
null
