Description:
With the ndb-6.3.x version of ndb_config warnings about ndb_mgmd and ndbd on the same host were printed to stderr (as expected), with ndb-7.0.4 the warnings are printed to stdout though which makes parsing and using the actual output of ndb_config next to impossible in shell scripts

How to repeat:
Create a minimal config.ini with ndb_mgmd and one ndbd on the same machine:

  [NDBD DEFAULT]
  NoOfReplicas= 2

  [NDB_MGMD]
  HostName = 192.169.1.1

  [NDBD]
  HostName = 192.169.1.1

  [NDBD]
  Hostname = 192.168.1.2

  [MYSQLD]

$ ndb-6.3.22/bin/ndb_config --config-file=config.minimal --query=DataMemory --type=ndbd 
Warning line 13: Cluster configuration warning:
  arbitrator with id 1 and db node with id 2 on same host 192.169.1.1
  Running arbitrator on the same host as a database node may
  cause complete cluster shutdown in case of host failure.

Suggested fix:
Make warnings go to stderr again

This also breaks ndb_error_reporter (bug #49160) so may need higher priority?

Breaks ndb_error_reporter

Documented in the NDB-7.0.10 changelog as follows:

        In MySQL Cluster NDB 7.0, ndb_config and ndb_error_reporter were
        printing warnings about management and data nodes running on the
        same host to stdout instead of stderr, as was the case in
        earlier MySQL Cluster release series.

        See also Bug #49160.

Closed.
