Artem Ervits commented on HBASE-18269:
--------------------------------------
[~mdrob] sure thing, I made the second example work with the following code
{code:java}
import java.lang
from org.apache.hadoop.hbase import TableName, HBaseConfiguration
from org.apache.hadoop.hbase.client import Connection, ConnectionFactory,
Result, ResultScanner, Table, Admin
from org.apache.hadoop.conf import Configuration
conf = HBaseConfiguration.create()
connection = ConnectionFactory.createConnection(conf)
admin = connection.getAdmin()
tableName = TableName.valueOf('wiki')
table = connection.getTable(tableName)
cf = "title"
attr = "attr"
scanner = table.getScanner(cf)
while 1:
result = scanner.next()
if not result:
break
print java.lang.String(result.row), java.lang.String(result.getValue(cf,
attr)){code}
Let me know if this suffices as the example uses result.get(col).value and I'm
getting
{code:java}
Traceback (most recent call last):
File "<stdin>", line 5, in <module>
AttributeError: 'org.apache.hadoop.hbase.client.Result' object has no attribute
'get'{code}
I changed to getValue instead and now actually use the CF and Qualifier. So the
only change in functionality is that I don't do cf="title:.*$" unless you can
hint at how I can do that here. I can work on the second example after that.
