在 hbase 中获取表区域状态的命令答案

【问题标题】：Command to get states of regions of a table in hbase在 hbase 中获取表区域状态的命令

【问题描述】：

如我所见here，HBase 为每个区域维护一个状态，并将该状态持久化在hbase:meta。

我无法获取获取表区域状态的命令。

通过运行以下命令：

scan 'hbase:meta',{FILTER=>"PrefixFilter('tableName')"}

我得到以下信息：

ROW                                                 COLUMN+CELL
 table-name,,1505804790891.ce656052407eb6 column=info:regioninfo, timestamp=1505804792579, value={ENCODED => ce656052407eb640b337d29d20e04e4c, NAME => 'table-name,,1505804790891.ce656

 40b337d29d20e04e4c.

我无法获取该区域的状态，请问如何获取该区域的状态。

这可能是一个错误，或者有人不小心从您的表格中删除了该列。因为对我来说，这很有效：

scan 'hbase:meta', {COLUMNS => 'info:state'}

输出：

ROW                                                                     COLUMN+CELL

显然您要查找的信息在info:state 列下。
