username@hostname:~$ python

>>>from passlib.context import CryptContext
>>>print CryptContext(['pbkdf2_sha512']).encrypt('PASSWORD')
$pbkdf2-sha512$25000$U.r9H4Ow9l5LiVHq3dt77w$q0f2q/WcDLD3I8/KzB3E4TqJ6vaKIXqWySE8HyRCzJXbh4N8wZtcJjN2zPQ5337PYep6IFFIUeoshUm1beMifg

Replace the PASSWORD with the appropriate password.

username@hostname:~$su - postgres_username
postgres_username@hostname:~$psql -t database_name
database_name=#UPDATE res_users SET password='', password_crypt='$pbkdf2-sha512$25000$U.r9H4Ow9l5LiVHq3dt77w$q0f2q/WcDLD3I8/KzB3E4TqJ6vaKIXqWySE8HyRCzJXbh4N8wZtcJjN2zPQ5337PYep6IFFIUeoshUm1beMifg' WHERE id=1;

 

Try the below solution.

  1. cd .metadata/.plugins
  2. mv org.eclipse.core.resources org.eclipse.core.resources.bak
  3. Start eclipse
  4. It will start but will show errors with opened tabs. This is because we have changed the resources folder, which eclipse use for managing the resources
  5. Close all opened tabs
  6. Exit from Eclipse
  7. Delete any newly create org.eclipse.core.resources folder
  8. Rename back the ‘org.eclipse.core.resources.bak’ to ‘org.eclipse.core.resources’
  9. Start Eclipse
  10. It should start fine with all projects

It worked for me.

Sometimes this issue may related to the protocol which we are using to connect with aws dynamodb. By default it is using the protocol https to connect with the AWS. So try the http protocol.

To resolve this issue try the below code:

amazonDynamoDBClient = new AmazonDynamoDBClient(credentials);
amazonDynamoDBClient .setEndpoint(“http:///”);

Note: replace the with the appropriate endpoint
