Major Description
New options for kafka.tools.ConsumerOffsetChecker:
--asjson - Json Output
--loop N - Loop interval (in seconds, greater than 0)
Both are optional/independent:
--asjson w/o --loop => Output as JSON, once and terminates
--loop w/o --asjson => Output in default tabular format, repeats on loop defined interval
--loop w/ --asjson => Output as JSON, repeats on loop defined interval
neither --asjson nor --loop => Current behavior, output in tabular format once and terminates
Patch to be attached.
