Stefan Miklosovic commented on CASSANDRA-18661:
-----------------------------------------------
While I definitely appreciate the effort in this ticket to make it on par with
other CLI tools, I would bring this to ML to see what broader audience thinks
about this. There is a ton of legacy online with all options, all the docs etc
so I wonder if we are not making more harm than good (even with very good
intentions). Maybe supporting the old and the new way at the same time would be
nice to have? Not sure how that would look like, I am just trying to figure out
how to be at least disruptive towards users as possible.
> Update 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
> Assignee: Claude Warren
> Priority: Normal
> Labels: lhf
>
> 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.
> Currently, there are > 5K lines of code in 'settings' which appears to just
> process command line args.
> 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}
>
> cassandra-stress -username foo -password bar
> {quote}and replacing the old syntax:
> {quote}
> cassandra-stress -mode username=foo and password=bar
>
> 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)
>
> Note: documentation will need to be updated as well
