> HdfsTableSink::Prepare throws an error if the table descriptor is missing.
> The error message should be something like: ‘ERROR: Failed to get table descriptor for table id: 0’
> Instead it looks like: ‘ERROR: 0ailed to get table descriptor for table id:’
> It happens because stringstream operator << overwrites the string in the constructor, in this case the beginning of the message with the table id.
> See: [Difference between constructor and operator << |https://stackoverflow.com/questions/49704052/c-stdstringstream-operator-vs-constructor]
> It would be nice to fix these error messages in the Backend.
