[jira] [Commented] (CASSANDRA-5653) NoSuchElementException using sstableloader when extra files (not Index/Data) exist under keyspace/CF of the restored folder

["Jonathan Ellis (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-5653?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13686407#comment-13686407 ] 

Jonathan Ellis commented on CASSANDRA-5653:
-------------------------------------------

It's true that if you have nonsense in the directory then it will choke, where "nonsense" is "files that don't belong to an sstable at all."  That looks like the case here; the exception indicates that it failed after parsing 2 tokens (delimited by "-"), and the minimum number of tokens in an sstable filename is 5.

> 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
