[−][src]Macro efflux::update_counter
Updates a counter for the current job.
A counter belongs to a group by a label; as such both must be given
to this macro in order to compile correctly. Note that neither the
group nor label can contain a ","
, as Hadoop uses this to split
the IO stream.
This is simply a sane wrapper around log!
to ensure that
counter updates are always logged in the correct formatting.
