Re: how to get the record number from hbase
hi hua,
using command

$ bin/hbase org.apache.hadoop.hbase.mapreduce.RowCounter <tablename>
[<column1> <column2>...]

it will report you the ROWS.
or you can write a MapReduce tool yourself to count the rows.

or you can run command in hbase shell:
hbase(main):005:0> scan 't1',FILTER=>"FirstKeyOnlyFilter()"
...
6 row(s) in 0.0730 seconds
this is a alternative choice for row count.

see HBase Reference Guide Chinese version: http://abloz.com/hbase/book.html
