Class HFileProcedurePrettyPrinter

java.lang.Object

org.apache.hadoop.hbase.util.AbstractHBaseTool

org.apache.hadoop.hbase.procedure2.store.region.HFileProcedurePrettyPrinter

All Implemented Interfaces:

org.apache.hadoop.conf.Configurable, org.apache.hadoop.util.Tool

@InterfaceAudience.LimitedPrivate(value="Tools")
 @InterfaceStability.Evolving
public class HFileProcedurePrettyPrinter
extends AbstractHBaseTool

A tool to dump the procedures in the HFiles.

The different between this and HFilePrettyPrinter is that, this class will decode the procedure in the cell for better debugging. You are free to use HFilePrettyPrinter to dump the same file as well.
