--echo # Queries such as SHOW TABLE STATUS and SELECT * FROM INFORMATION_SCHEMA.TABLES fail
5
--echo # when encountering a federated table that cannot connect to its remote table.
7
--echo # The fix is to store the error text in the TABLE COMMENTS column of I_S.TABLES, clear
8
--echo # the remote connection error and push a warning instead. This allows the SELECT operation
9
--echo # to complete while still indicating a problem. This fix applies to any non-fatal system
