显示表配置的Hbase shell命令。

Question

我在HBase的

创建表

create 'test', 'x', 'y', 'z', {NUMREGIONS => 10, SPLITALGO => 'UniformSplit'}

当我发出describe 'test'

hbase(main):016:0> describe 'test' Table test is ENABLED test COLUMN FAMILIES DESCRIPTION {NAME => 'x', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER', COMPRESSION => 'NONE', MIN_VERSIONS => '0', BLOCK CACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'} {NAME => 'y', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER', COMPRESSION => 'NONE', MIN_VERSIONS => '0', BLOCK CACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'} {NAME => 'z', BLOOMFILTER => 'ROW', VERSIONS => '1', IN_MEMORY => 'false', KEEP_DELETED_CELLS => 'FALSE', DATA_BLOCK_ENCODING => 'NONE', TTL => 'FOREVER', COMPRESSION => 'NONE', MIN_VERSIONS => '0', BLOCK CACHE => 'true', BLOCKSIZE => '65536', REPLICATION_SCOPE => '0'} 3 row(s) in 0.0170 seconds

describe命令不显示SPLITALGO和NUMREGIONS。

是否有HBase shell命令显示表配置？

Answer 1

我想有没有简单的方法，但你可以通过

(get_splits "YourTableName").count 

获取区域的数量
