Deleting an Index

Scenarios

You can use the GSI tool to delete an index.

How to Use

Run the following command on the HBase client to delete an index:

hbase org.apache.hadoop.hbase.hindex.global.mapreduce.GlobalTableIndexer -Dtablename.to.index='table' -Dindexnames.to.drop='idx1#idx2'

The parameters are described as follows:

• tablename.to.index: indicates the name of the table where the index to be deleted is.
• indexnames.to.drop: indicates the name of the index to be deleted. You can specify multiple indexes and separate them with number signs (#).
