Use ${HADOOP_HOME}/bin/hadoop fs -dus <hbase.rootdir> to see size in 
hdfs (or ${HADOOP_HOME}/bin/hadoop fs -lsr <hbase.rootdir> to see 
listing and size of individual files).

If you want to know how many rows, etc., you can run 'select * from 
YOUR_TABLENAME;' or even 'select count(*) from YOUR_TABLENAME;'.  If 
your table is big, the latter will take a long time (HADOOP-2291 is 
sampling to estimate the overall count, a process that should take less 
time).
