Hi,
I am using hbase connection pooling using
HConnection hConnection=HConnectionManager.createConnection(conf);
I see most of method of HConnectionManager goes to depreciated.
Please provide to me best way to create Hbase connection pool and what your
future plan for this topic.
thanks
HConnection is also deprecated. It would be better to do:
Connection connection = ConnectionFactory.createConnection(conf);

Can you please share your log4j.properties file? Just cut&past the content

For a 'fix' and 'recover' hfile tool at HBase level, the relatively easy
thing we can recover is probably the data (KVs) up to the point when we hit
the first corruption caused exception.
After that, it will not be as easy. For example, if the current key length
or value length is bad, there is n
Realistically this should be weighed by number of machines.If you run a small 5

much as somebody who's running 1000 machines.

Hi,
I have hbase scan with some filters. If the scan going through 1 million
rows then the filters reduce it down to 100 rows to send back to the client.
How can I know that the scan went through 1 million rows? Is it possible to
see it from the ResultScanner?
Thanks,

In 1.0+ API, there's no more automatic pooling. You application uses the
ConnectionFactory (as Solomon says) to get a connection instance for the
application, and retrieve accessor objects (Table, Admin, &c) from that
singleton.

My only complaint about this poll is the labels: "0.94.x - I like stable

about the extremely difficulty of overcoming "the singularity" from 0.94 ->

I don't think so.

If you haven't already seen it - take a look at the bridge at

We're using it to go through the process now.

On the high level, the tool will read/scan the KVs from the hfile similar
to what the HFile tool does, while opening a HFileWriter to dump the good
