I have verified that all the NDB executables were built, but where are the columns for
NDB? They should be present, and have the value DISABLED.

Were the server built without NDB support at all, then the columns should also be there,
but have the value NO.

      Bug#29263 disabled storage engines omitted in SHOW ENGINES
      Static disabled plugins|engines and dynamic plugins which installed but disabled
      are not visible in I_S PLUGINS|ENGINES tables because they are not stored into
      global plugin array.
      The fix: add such plugins|engines to plugin array with PLUGIN_IS_DISABLED status.
      I_S.ENGINES 'Transactions', 'XA', 'Savepoints' fields have NULL value in this case.

Noted in 5.1.31, 6.0.10 changelog.

Static storage engines and plugins that were disabled and dynamic
plugins that were instaled but disabled were not listed in the
INFORMATION_SCHEMA appropriate PLUGINS or ENGINES table.

Note that the "repair" of this "problem" has led to another problem, one we consider more important than this one: "Dynamic plugin broken in 5.1.31" http://bugs.mysql.com/bug.php?id=42610.

Is there any solution to overcome the in built plugin..If so pl..post the solution for this issue...
