Here is some help for this command:
Count the number of rows in a table. This operation may take a LONG
time (Run '$HADOOP_HOME/bin/hadoop jar hbase.jar rowcount' to run a
counting mapreduce job). Current count is shown every 1000 rows by
default. Count interval may be optionally specified. Scan caching
is enabled on count scans by default. Default cache size is 10 rows.
If your rows are small in size, you may want to increase this
parameter. Examples:

 hbase> count 't1'
 hbase> count 't1', INTERVAL => 100000
 hbase> count 't1', CACHE => 1000
 hbase> count 't1', INTERVAL => 10, CACHE => 1000
