*Size of sstable : 2 GB*
*Note: I ran a major compaction before running this command.*


How can I fix this?

Also does sstablesplit internally invoke compaction?

How much heap is available to the JVM sstablesplit is running in? Increase
it.

This version has serious known bugs, update to the most recent 2.0.x
version ASAP.

The source code is available... :D

As a safety note, please be sure to run sstablesplit either outside of the
data directory or with the cassandra node stopped.
