HBase Consistency Checker 2 (HBCK2)

HBCK2 is a command-line tool that helps administrators maintain the consistency and health of Apache HBase clusters.

It provides a collection of commands to detect and repair inconsistencies in hbase:meta, region assignments, table and region states, replication metadata, and the underlying HDFS filesystem.

HBCK2 is designed to complement HBase’s built-in recovery mechanisms and offers targeted repair actions for scenarios where automated recovery is insufficient.
