hi all,
I am new to hbase and encounter a problem of client connection. I
download latest stable version(0.94.15) and start the server
successfully. And I can use ./bin/hbase shell to connect to server in
local, But I can't connect to the server using a remote java client.
My setup configures:
1. OS
Centos 5.5
2. HBase
0.94.15 standalone mode
3. hbase-site.xml
<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///home/lili/hbasedata</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/home/lili/zookeeperdata</value>
</property>
<property>
<name>hbase.master.port</name>
<value>61000</value>
</property>
<property>
<name>hbase.master.info.port</name>
<value>61010</value>
</property>
<property>
<name>hbase.regionserver.port</name>
<value>61020</value>
</property>
<property>
<name>hbase.regionserver.info.port</name>
<value>61030</value>
</property>
<property>
<name>hbase.zookeeper.leaderport</name>
<value>63888</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>62181</value>
</property>
<property>
<name>hbase.rest.port</name>
<value>58080</value>
</property>
</configuration>
4. remote http test to master
http://server-ip:61010/master-status correct
5. region server http
http://server-ip::61030 correct
6. remote client test(windows)
telnet server-ip 62181 correct
7. java program
Configuration myConf = HBaseConfiguration.create();
myConf.set("hbase.zookeeper.quorum", "172.19.34.35");
myConf.set("hbase.zookeeper.property.clientPort", "62181");
HTableInterface usersTable = new HTable(myConf, "users");
{
Put p = new Put(Bytes.toBytes("TheRealMT"));
p.add(Bytes.toBytes("info"), Bytes.toBytes("name"),
Bytes.toBytes("Mark Twain"));
p.add(Bytes.toBytes("info"), Bytes.toBytes("email"),
Bytes.toBytes("[email protected]"));
p.add(Bytes.toBytes("info"), Bytes.toBytes("password"),
Bytes.toBytes("Langhorne"));
usersTable.put(p);
}
{
Put p = new Put(Bytes.toBytes("TheRealMT"));
p.add(Bytes.toBytes("info"),
Bytes.toBytes("password"),
Bytes.toBytes("abc123"));
usersTable.put(p);
}
usersTable.close();
When runing this program, it hangs at this line: HTableInterface
usersTable = new HTable(myConf, "users");
I have checked in hbase shell by scan 'users', it's an empty table
After very long time, it throws an exception:
