Jonathan Ellis resolved CASSANDRA-5653.
---------------------------------------

    Resolution: Not A Problem

I looked into catching the error and found that this was already done for CASSANDRA-5587.

You really need to test against the current branch unless you're specifically trying to reproduce an error reported against an older version.  (Even then, we will want to know, "did you try it against the current branch? because it might already be fixed.")

> 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
