The sstablescrub utility

An offline version of nodetool scrub. This tool attempts to remove the corrupted parts while preserving non-corrupted data.

Use this tool to fix (throw away) corrupted tables. Before using this tool, try rebuild the tables using nodetool scrub. Because corrupted rows are thrown away, run a repair after running this tool.
