Querying an Index
After an index is created, you can run commands to query index information, including the index column definition, covering column definition, and index status.
How to Use
Run the following command to view the index definition and status:
hbase com.huawei.boostkit.hindex.mapreduce.GlobalTableIndexer -Dtablename.to.show=tablename
The command output displays the index column definition, covering column definition, and index status:
1 2 3 | The index information of table : IndexName : idx_0, IndexColumns : [cf_0:q_0 -> type:STRING, cf_0:q_1 -> type:STRING], CoveredColumns : [cf_0:q_0 -> type:STRING], IndexState : ACTIVE IndexName : idx_1, IndexColumns : [cf_0:q_0 -> type:STRING, cf_0:q_1 -> type:STRING, cf_0:q_2 -> type:STRING], CoveredColumns : [], IndexState : ACTIVE |
