Jay Kreps commented on KAFKA-313:
---------------------------------
Is JSON better than CSV for this kind of thing? CSV is sometimes more shell
friendly and that is what we are using for the perf tests...
If we like JSON then I am +1
> Add JSON output and looping options to ConsumerOffsetChecker

> Key: KAFKA-313
> URL: https://issues.apache.org/jira/browse/KAFKA-313
> Project: Kafka
> Issue Type: Improvement
> Reporter: Dave DeMaagd
> Priority: Minor
> Labels: patch
> Fix For: 0.8

> Adds:
> * '--loop N' - causes the program to loop forever, sleeping for up to N
> seconds between loops (loop time minus collection time, unless that's less
> than 0, at which point it will just run again immediately)
> * '--asjson' - display as a JSON string instead of the more human readable
> output format.
> Neither of the above depend on each other (you can loop in the human
> readable output, or do a single shot execution with JSON output). Existing
> behavior/output maintained if neither of the above are used. Diff Attached.
> Impacted files:
> core/src/main/scala/kafka/tools/ConsumerOffsetChecker.scala
