Get column data from HBase via JRuby script

I can get value for certain column in HBase table via hbase shell:

hbase(main):002:0> scan 'some_table', {STARTROW => '7af02800f4c6478cde0f55e8bce34f4a2efa48f2', LIMIT => 1, COLUMNS => ['foo:bar']}
ROW                                         COLUMN+CELL
 7af02800f4c6478cde0f55e8bce34f4a2efa48f2   column=foo:bar, timestamp=0, value=http://someurl.com/some/path
1 row(s) in 0.4430 seconds

I would like to reproduce the same with jruby script. The following is my approach.

include Java
import org.apache.hadoop.hbase.HBaseConfiguration
import org.apache.hadoop.hbase.client.HTable
import org.apache.hadoop.hbase.client.Get

tableName = 'some_table'
conf = HBaseConfiguration.create
ht = HTable.new(conf, tableName)
key = '7af02800f4c6478cde0f55e8bce34f4a2efa48f2'
my_get = Get.new(key.to_java_bytes)
result = ht.get(my_get)

# And what to do now?

What is the correct way to obtain column value from HBase table via JRuby?

Solution

include Java
import org.apache.hadoop.hbase.HBaseConfiguration
import org.apache.hadoop.hbase.client.HTable
import org.apache.hadoop.hbase.client.Get
import org.apache.hadoop.hbase.util.Bytes

tableName = 'some_table'
conf = HBaseConfiguration.create
ht = HTable.new(conf, tableName)
key = '7af02800f4c6478cde0f55e8bce34f4a2efa48f2'
my_get = Get.new(key.to_java_bytes)
result = ht.get(my_get)

# This
puts Bytes.toStringBinary(result.getValue('foo'.to_java_bytes, 'bar'.to_java_bytes))
