> The options {{-k}} and {{-x}} of {{sstabledump}} admit multiple arguments, so
> users can include or exclude multiple partitions. The intended usage is, for
> example:
> {code:java}
> $ sstablepartitions <sstable_path> -k 1
> $ sstablepartitions <sstable_path> -k 1 2 3
> {code}
> However, the following command will fail:
> {code:java}
> $ sstablepartitions -k 1 <sstable_path>
> You must supply exactly one sstable
> usage: sstabledump <sstable file path> <options>
> Dump contents of given SSTable to standard output in JSON format.
> -d CQL row per line internal representation
> -e enumerate partition keys only
> -k <arg> Partition key
> -t Print raw timestamps instead of iso8601 date strings
> -x <arg> Excluded partition key
> {code}
> This command fails because the sstable path is considered a fourth partition
> key, and the mandatory argument for the sstable path is missed. While I think
> this behaviour is correct, it can be a bit confusing for users, especially
> when the information about usage describes both {{-k}} and {{-x}} as
> single-argument.
> I think that at least we should fix the description of the options to
> indicate that there could be multiple included/excluded keys, and probably
> improve the message about the missing sstable path when those options are
> used.
> Alternatively we could modify the options to have a single argument and allow
> to repeat them, so we could accept things like:
> {code:java}
> $ sstablepartitions -k 1 <sstable_path>
> $ sstablepartitions -k 1 -k 2 -k 3 <sstable_path>
> $ sstablepartitions <sstable_path> -k 1 -k 2 -k 3
> {code}
> The main downside of the latter approach is that the change in the syntax of
> the command might cause compatibility issues. Also we would need to upgrade
> {{commons-cli}} to at least 1.2 due to CLI-137.
