------------------------------------------
Summary: Update to cassandra-stress to use Apache Commons CLI
Key: CASSANDRA-18661
URL: https://issues.apache.org/jira/browse/CASSANDRA-18661
Project: Cassandra
Issue Type: Improvement
Components: Tool/stress
Reporter: Brad Schoening
The Apache Commons CLI library provides an API for parsing command line options
with the package org.apache.commons.cli and this is already used by a dozen of
existing Cassandra utilities including:
{quote}SSTableMetadataViewer, StandaloneScrubber, StandaloneSplitter,
SSTableExport, BulkLoader, and others.{quote}
However, cassandra-stress is an outlier which uses its own custom classes to
parse command line options with classes such as OptionsSimple. In addition,
the options syntax for username, password, and others are not aligned with the
format used by CQLSH.
This suggestion is to:
a) Upgrade cassandra-stress to use Apache Commons CLI (no new dependencies are
required as this library is already used by the project)
b) Align the cassandra-stress CLI options with those in CQLSH,
{quote}For example, using the new syntax like CQLSH:{quote}
{quote}{quote}cassandra-stress -username foo -password bar{quote}
and replacing the old syntax:{quote}
{quote}{quote}cassandra-stress -mode username=foo and password=bar{quote}{quote}
This will simplify and unify the code base, eliminate code and reduce the
confusion between similar named classes such as
org.apache.cassandra.stress.settings.\{Option, OptionsMulti, OptionsSimple} and
org.apache.commons.cli.{Option, OptionGroup, Options)
