Noemi Pap-Takacs updated IMPALA-12717:
--------------------------------------
Description:
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.

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 is likely because of incorrect stringstream usage, overwriting the beginning
of the message with the table id.
