MR example job to count table rows
----------------------------------
Key: HBASE-559
URL: https://issues.apache.org/jira/browse/HBASE-559
Project: Hadoop HBase
Issue Type: Bug
Reporter: stack
The Lars' import is a little messy; he's not sure how many records were
imported. Running a select takes a couple of hours. He happens to have an
idle MR cluster standing by. An example MR job that just did a count of
records would be generally useful. Could even output row keys so you'd have a
list of what made it in. Later, if this tool becomes popular with derivatives
and similiars, we can bundle a jar of MR jobs to run against your tables that
can answer common queries and that are amenable to subclassing/modification.
