In version 1.7.6, you may see this kind of log in galactica logs (indexima_current.log or hive.log).

TSaslTransportException: No data or no sasl data in the stream

This is only a warning message and has no effect on the behavior of your indexima cluster.

It is due to Developer Console which is testing if the host of your project is up or not.

This check is interesting if you are often changing the hosts of your indexima cluster and you are using the http transport mode.

It will be disabled in 1.7.7 version and above.

If you want to enable this behavior, you will have to set the following environment variable in the file of Developer Console.
