> Oozie instrumentation logs contain a lot of information, but are difficult to
> parse, because per instrumentation log entry there is always one header line
> in plain text format (containing timestamp), and multiple other lines in JSON
> format (not containing timestamp). Those lines of course belong together.

> There should be a simple script in {{tools/bin}} that takes as parameters:
> * input file name ({{-i}}), e.g. {{-i /path/to/oozie-instrumentation.log}}
> * output file name ({{-o}}), e.g. {{-o
> /path/to/oozie-instrumentation.log.out}}
> * parameters to extract ({{-p}}) in the format of
> {{path/to/json/value1,path/to/json/value2}}, in this case {{-p
> counters/callablequeue/executed/count,counters/callablequeue/queued/count}}
> The output file should contain in CSV format:
> * a header line containing column names for
> * one line per parsed input header / JSON lines, containing:
> ** first cell is the minutes part of the timestamp
> ** consecutive cells are parsed JSON values given each parameter to extract
