如何将 HBase table 强制到区域服务器
How to force an HBase table to a region server
我有 2 个 Hbase 表，我想将它们中的每一个强制到不同的区域服务器。有没有办法告诉 HBase 这样做？
您可以使用 hbase shell 移动命令将区域移动到另一个区域服务器：
hbase> move ‘ENCODED_REGIONNAME’, ‘SERVER_NAME’
Move a region. Optionally specify target regionserver else we choose
one at random. NOTE: You pass the encoded region name, not the region
name so this command is a little different to the others. The encoded
region name is the hash suffix on region names: e.g. if the region
name were
TestTable,0094429456,1289497600452.527db22f95c8a9e0116f0cc13c680396.
then the encoded region name portion is
527db22f95c8a9e0116f0cc13c680396 A server name is its host, port plus
startcode. For example: host187.example.com,60020,1289493121758

虽然如果两个表都很大，它们可以在集群中的每个 RegionServer 上都有区域，所以我不确定您要用它完成什么。
