RowCounter is a utility that will count all the rows of a table. This is a good utility to use as a sanity check to ensure that HBase can read all the blocks of a table if there are any concerns of metadata inconsistency. $ bin/hbase org.apache.hadoop.hbase.mapreduce.RowCounter <tablename> [<column1> <column2>...] Note: caching for the input Scan is configured via hbase.client.scanner.caching in the job configuration. ------ http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/filter/FirstKeyOnlyFilter.html http://comments.gmane.org/gmane.comp.java.hadoop.hbase.user/18124 On Thu, Jan 26, 2012 at 12:57 AM, illuvatar <andrea.pontrando...@hotmail.it>wrote: > > Hi everyone, i have a problem. > I'm trying to count for java the number of row in a table, but i can't do > it!! > I read about rowCounter, but i can't use it.
