Querying Indexes
Scenario
You can use the GSI tool to view the definition and status of indexes of a data table in batches.
Usage
Run the following command on the HBase client to view the definition and status of an index:
hbase org.apache.hadoop.hbase.hindex.global.mapreduce.GlobalTableIndexer -Dtablename.to.show='table'
The related parameters are described as follows:
tablename.to.show: indicates the name of the table where the index to be queried is.
Figure 1 shows the query result. The index column definition, covering column definition, TTL, pre-partition information, and index status are displayed.
