1）移动region

语法：move 'encodeRegionName', 'ServerName'

encodeRegionName指的regioName后面的编码，ServerName指的是master-status的Region Servers列表

示例

hbase(main)>move '4343995a58be8e5bbc739af1e91cd72d', 'db-41.xxx.xxx.org,60020,1390274516739'

2）开启/关闭region

语法：balance_switch true|false

hbase(main)> balance_switch

3）手动split

语法：split 'regionName', 'splitKey'

4）手动触发major compaction #语法： #Compact all regions in a table: #hbase> major_compact 't1' #Compact an entire region: #hbase> major_compact 'r1' #Compact a single column family within a region: #hbase> major_compact 'r1', 'c1' #Compact a single column family within a table: #hbase> major_compact 't1', 'c1'
