HBCK 2 Commands

HBCK2 provides a collection of administrative tools for diagnosing and repairing inconsistencies in HBase clusters.

These commands help identify metadata problems, correct region and table state issues, recover from RegionServer failures, and resolve filesystem-level corruption.

Most commands are designed for targeted, minimal-impact repairs, while others offer low-level recovery actions that should be used only as a last resort. Use these tools to restore cluster health when automated recovery is insufficient.
