Body
HBase stores data as byte arrays (untyped). Therefore if you perform a table scan data will be displayed in a <a href="http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/util/Bytes.html#toStringBinary%28byte%5B%5D,%20int,%20int%29" rel="noreferrer">common format</a> (escaped hexadecimal string), e.g: "\x48\x65\x6c\x6c\x6f\x20\x48\x42\x61\x73\x65" -> Hello HBase If you want to get back the typed value from the serialized byte array you have to do this manually. You have the following options: <ul> <li>Java code (Bytes.toString(...))</li> <li>hack the to_string function in <code>$HBASE/HOME/lib/ruby/hbase/table.rb</code> : replace toStringBinary with toInt for non-meta tables</li> <li>write a get/scan JRuby function which converts the byte array to the appropriate type</li> </ul> Since you want it HBase shell, then consider the last option: Create a file get_result.rb : <pre><code>import org.apache.hadoop.hbase.HBaseConfiguration import org.apache.hadoop.hbase.client.HTable import org.apache.hadoop.hbase.client.Scan; import org.apache.hadoop.hbase.util.Bytes; import org.apache.hadoop.hbase.client.ResultScanner; import org.apache.hadoop.hbase.client.Result; import java.util.ArrayList; # Simple function equivalent to scan 'test', {COLUMNS => 'c:c2'} def get_result() htable = HTable.new(HBaseConfiguration.new, "test") rs = htable.getScanner(Bytes.toBytes("c"), Bytes.toBytes("c2")) output = ArrayList.new output.add "ROW\t\t\t\t\t\tCOLUMN\+CELL" rs.each { |r| r.raw.each { |kv| row = Bytes.toString(kv.getRow) fam = Bytes.toString(kv.getFamily) ql = Bytes.toString(kv.getQualifier) ts = kv.getTimestamp val = Bytes.toInt(kv.getValue) output.add " #{row} \t\t\t\t\t\t column=#{fam}:#{ql}, timestamp=#{ts}, value=#{val}" } } output.each {|line| puts "#{line}\n"} end </code></pre> load it in the HBase shell and use it: <pre><code>require '/path/to/get_result' get_result </code></pre> Note: modify/enhance/fix the code according to your needs

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
