Thanks for the response JD,
i modified the code according to ur suggesstion.
and i want to display the number of rows:
for example
09/08/14 15:40:01 INFO mapred.JobClient: RowCounter
09/08/14 15:40:01 INFO mapred.JobClient: Rows=171
so ideally the below code should print 171 right:
Counters c = JobClient.runJob(rowCounter.createSubmittableJob(new
String[]{"/user/root/rowCount",TableDefinations.KEYWORD_TABLE,
TableDefinations.COLUMN_FAMILY_TIMESTAMP})).getCounters();
System.out.println(c.getGroup("RowCounter").getCounter("Rows"));
but its displays 0. i tried lot of other options as well. but no luck.
there is also a call
c.getCounter(Enum key). but coudnt find any Predefined Enums in RowCounter.
Regards,
Raakhi
