Jonathan Ellis commented on CASSANDRA-4273:
-------------------------------------------
But we're not talking about log messages.
> Write auxiliary info to the system's error stream and not to the std output.

> Key: CASSANDRA-4273
> URL: https://issues.apache.org/jira/browse/CASSANDRA-4273
> Project: Cassandra
> Issue Type: Improvement
> Components: API, Tools
> Affects Versions: 1.1.0, 1.2
> Environment: Ubuntu 10.04 LTS with Sun Java 1.6.0.26
> Using Cassandra without JNA
> Reporter: Pantelis Sopasakis
> Priority: Minor
> Labels: cassandra-cli
>
> When executing a Cassandra script from the terminal then all output is
> written to the standard output stream of the system. For example if we create
> a file called my_script with the following commands:
> use MyKeyspace;
> show schema;
> and we execute it as:
> cassandra-cli < my_script > my.scm
> then the output file my.scm will also contain lines like:
> Connected to: "Test Cluster" on 127.0.0.1/9160
> Welcome to Cassandra CLI version 1.2.0-SNAPSHOT
> Type 'help;' or '?' for help.
> Type 'quit;' or 'exit;' to quit.
> or
> Authenticated to keyspace: MyKeyspace
> Would be good to write such information to the system error stream so that
> one would be able to do:
> cassandra-cli < my_script > my.scm 2> /dev/null
