--------------------------------
Summary: make cpp client example error message for mistyped master
easier to understand
Key: KUDU-3439
URL: https://issues.apache.org/jira/browse/KUDU-3439
Project: Kudu
Issue Type: Wish
Components: client
Reporter: Bakai Ádám
If the user mistypes the master address, then he gets a very long error
message. It definitely contains the useful part ("Could not connect to the
cluster: unable to resolve address for localhosta: nodename nor servname
provided, or not known") , but there are so many lines it's kind of hard to
find:
