Hello  sreenivasulu ,

Thank you for the bug report.
This is most likely duplicate of Bug #87785, please see Bug #87785

Thanks,
Chiranjeevi.

Sry for this issue, it's not a bug this is setup issue .

follow as below

Goto Edit-->Preferences-->Administration

here, shows three input fields like 

1. Path to mysqldump tool [choose path with fileName (/path/filename)]
2. path to mysql tool [(/path/filename)] 
   ----> Ex: /usr/bin/mysql
3 Export Directory path [shows where ever you want to export data[path]]

Setting the Administration Paths does NOT fix the problem.
When will this be fixed.
Surely it is Important to be able to Export Databases for Backup, etc.
I cannot believe this has not been fixed given that it was reported by myself and other long before...
Thanks

One cause of this error is that mysqldump may produce warnings when asked for a version number. Check the wb.log; if it contains something like:

mysqldump: [Warning] World-writable config file '/etc/mysql/my.cnf' is ignored.

or some other waning from mysqldump, fix whatever generates that warning (in this case, don't let your config files be world-writeable; that's a security risk).

If this is the cause, then the bug is that WB should ignore any lines containing [Warning] when determining the version number.

I noticed that if you have multiple versions of mysql on your machine, and my.cnf is related to the older version, the potentially innocuous message "my.cnf is ignored" appears.  However, when I rename this file, the Workbench suddenly works.  Perhaps a more detailed suggestion would help...
