Description:
An exception is thrown by dump sharding_information commands when no shards are inside a definition / setup.
How to repeat:
1.- Check dump sharding information commands.
bash-4.1$ mysqlfabric dump sharding_information
Command :
{ success = True
return = [0, 0, 1, [['oltp', 'oltp', 'emp_no', '30001', '2', 'RANGE', 'my_group2', 'my_group4']]]
activities =
}
2.- Ensure no shards remain in setup, if they are remove them
-bash-4.1$ mysqlfabric sharding disable_shard 2
Procedure :
{ uuid = ed0ddb21-2c96-47a6-ba53-39c6308057d1,
finished = True,
success = True,
return = True,
activities =
}
-bash-4.1$ mysqlfabric sharding remove_shard 2
Procedure :
{ uuid = 4c0d04fb-a8ba-4d26-99fb-d432c7103518,
finished = True,
success = True,
return = True,
activities =
}
3.- Try dump sharding_information and you will get an exception
-bash-4.1$ mysqlfabric dump sharding_information

Suggested fix:
Message indicating no shard exist should be prompted.
