Pantelis Sopasakis created CASSANDRA-4273:
---------------------------------------------
Summary: 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
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
