Hbase Java Client
Hi
I have written a small program to connect to hbase but it stuck half way and
just go in the wait state.
*Here is the code
* System.out.println("Start");
HBaseConfiguration config = new HBaseConfiguration();
config.clear();
config.set("hbase.zookeeper.quorum", "10.10.10.2:2181");
config.set("hbase.zookeeper.property.clientPort","2181");
System.out.println("Before Htable");
HTable table = new HTable(config, "rnc");
System.out.println("After Htable");
System.out.println("Before Get");
Get g = new Get(Bytes.toBytes("20100926000000P123TREDFR$#"));
Result r = table.get(g);
byte [] value = r.getValue(Bytes.toBytes("Info"),
Bytes.toBytes("COL_STAGE"));
// If we convert the value bytes, we should get back 'Some Value', the
// value we inserted at this location.
String valueStr = Bytes.toString(value);
System.out.println("GET: " + valueStr);
*And here is the system Output*
*Start*
10/10/29 02:05:46 WARN hbase.HBaseConfiguration: instantiating
HBaseConfiguration() is deprecated. Please use HBaseConfiguration#create()
to construct a plain Configuration

Hi J-D,
I have solved the problem. The problem was that server has latest CDHb3 jars
while client has old CDHb2 jars. I have replaced the client jars and it
starts working,
Thanks

Re: Hbase Java Client
Posted by Jean-Daniel Cryans <jd...@apache.org>.
According to the log it seems that you have a flaky VPN connection, or
some weirdness like that. In one case your client wasn't able to talk
to the ZK server for 26 seconds, which is kind of a huge deal. You
should look into that.

Re: Hbase Java Client
Posted by Shuja Rehman <sh...@gmail.com>.
Hi
I have checked the given link. According to it, it does not work from
windows platform. Let me explain the whole scenario. I have cluster of 4
machines on which ubuntu is running. I have connected to this cluster using
VPN and i have windows 7 installed and i am using netbeans to develop the
program. So is there anyway to find the problem?
one progress in output. it prints one more line in addition to previous
output. here is the output from the end.
10/10/29 18:40:32 INFO zookeeper.ClientCnxn: Opening socket connection to

Can anybody here to sort out this issue?
