ndb_drop_index (1) Linux Manual Page

Usage:

ndb_drop_index -c connect_string table_name index -d db_name

The statement shown above drops the index named index from the table in the database.

Additional Options: None that are specific to this application.

Warning

Operations performed on Cluster table indexes using the NDB API are not visible to MySQL and make the table unusable by a MySQL server. If you use this program to drop an index, then try to access the table from an SQL node, an error results, as shown here:

shell> ./ndb_drop_index -c localhost dogs ix -d ctest1

Dropping index dogs/idx…OK

NDBT_ProgramExit: 0 – OK

shell> ./mysql -u jon -p ctest1

Enter password: *******

ERROR 1296 (HY000): Got error 4243 ‘Index not found’ from NDBCLUSTER

In such a case, your only option for making the table available to MySQL again is to drop the table and re-create it. You can use either the SQL statementDROP TABLE or the ndb_drop_table utility (see ndb_drop_table(1)) to drop the table.
