Class MobStressToolRunner

java.lang.Object

org.apache.hadoop.hbase.mob.MobStressToolRunner

public class MobStressToolRunner
extends Object

Reproduction for MOB data loss 1. Settings: Region Size 200 MB, Flush threshold 800 KB. 2. Insert 10 Million records 3. MOB Compaction and Archiver a) Trigger MOB Compaction (every 2 minutes) b) Trigger major compaction (every 2 minutes) c) Trigger archive cleaner (every 3 minutes) 4. Validate MOB data after complete data load. This class is used by MobStressTool only. This is not a unit test
