ndb_show_tables displays a list of allNDB database objects in the cluster. By default, this includes not only both user-created tables and NDB system tables, butNDB-specific indexes, internal triggers, and NDB Cluster Disk Data objects as well.

Options that can be used with ndb_show_tables are shown in the following table. Additional descriptions follow the table.

A directory reference may be relative or absolute; it may contain one or more environment variables, each denoted by a prefixed dollar sign ($), and expanded prior to use.
  Searching begins with the leftmost named directory and proceeds from left to right until a file is found. An empty string denotes an empty search path, which causes all searches to fail. A string consisting of a single dot (.) indicates that the search path limited to the current working directory.
  If no search path is supplied, the compiled-in default value is used. This value depends on the platform used: On Windows, this is \ndb-tls; on other platforms (including Linux), it is$HOME/ndb-tls. This can be overridden by compiling NDB Cluster using-DWITH_NDB_TLS_SEARCH_PATH.
