Description

Design Objective:

1. Merge empty region
2. Neat region
3. merge expired region

Usage: bin/hbase onlinemerge [--tableName=] [--startRegion=] [--stopRegion=] [--maxRegionSize=] [--maxRegionCreateTime=] [--numMaxMergePlans=] [--targetRegionCount=] [--printExecutionPlan=] [--configMergePauseTime=]

Options:
--h or --h print help
--tableName table name must be not null
--startRegion start region
--stopRegion stop region
--maxRegionSize max region size Unit GB
--maxRegionCreateTime max Region Create Time yyyy/MM/dd HH:mm:ss
--numMaxMergePlans num MaxMerge Plans
--targetRegionCount target Region Count
--configMergePauseTime config Merge Pause Time In milliseconds
--printExecutionPlan Value default is true print execution plans false is execution merge

Examples:
bin/hbase onlinemerge --tableName=test:test1 --startRegion=test:test1,,1576835912332.01d0d6c2b41e204104524d9aec6074fb. --stopRegion=test:test1,bbbbbbbb,1573044786980.0c9b5bd93f3b19eb9bd1a1011ddff66f. --maxRegionSize=0 --maxRegionCreateTime=yyyy/MM/dd HH:mm:ss --numMaxMergePlans=2 --targetRegionCount=4 --printExecutionPlan=false
