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'
