I have been looking at the stuff in the zip file, and also the 
sstablesplit command script. This script is looking for a java
class StandaloneSplitter located in the package org.apache.cassandra.tools.

Where is this package located ? I looked in the lib directory but nothing contains 
the class. Is this something I need to get as well ?

I saw that msg in the thread, I pulled the git files and it looks
like a suite of tools, do I install them on their own ? do I replace the
current ones ? its production data but I can copy the data to where
I want and experiment.

Does this help ? http://www.mail-archive.com/user@cassandra.apache.org/msg30973.html

Can you pull the data off the node so you can test it somewhere safe ?

Thanks, this does look like what I'm experiencing. Can someone 
post a walkthrough ? The README and the sstablesplit script 
don't seem to cover it use in any detail.

Take a look at the very recent thread called 'Alternate "major compaction"'. There are some ideas in there about splitting up a large SSTable.

Hi all,

Is there a way to get an SSTable to a smaller size ? By this I mean that I 
currently have an SSTable that is nearly 1.2G, so that subsequent SSTables
when they compact are trying to grow to that size. The result is that when 
the min_compaction_threshold reaches it value and a compaction is needed, 
the compaction is taking a long time as the file grows (it is currently at 52MB and
takes ~22s to compact).

I'm not sure how the SSTable initially grew to its current size of 1.2G, since the
servers have been up for a couple of years. I hadn't noticed until I just upgraded to 1.2.6,
but now I see it affects everything.
