Hi Nick
I've changed my code so it runs with the HBase Java API 0.98.7-hadoop2
trying to connect to my HBase 0.98.7 installation in my laptop. My
hbase-site.xml in the HBase software and CLASSPATH file are this:
<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///C:/Desarrollo/hbase-0.98.7-hadoop2/data/hbase</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>C:\Desarrollo\hbase-0.98.7-hadoop2\data\zookeeper</value>
</property>
<property>
<name>hbase.zookeeper.property.clientPort</name>
<value>2181</value>
</property>
<property>
<name>hbase.master.port</name>
<value>60000</value>
</property>
<property>
<name>hbase.master.info.port</name>
<value>60010</value>
</property>
<property>
<name>hbase.regionserver.port</name>
<value>60020</value>
</property>
<property>
<name>hbase.regionserver.info.port</name>
<value>60030</value>
</property>
</configuration>
When my application tries to create the HBaseAdmin object it takes
approximately 12 seconds and when it tries to create a table it hangs.
There are no visible errors in the HBase console.
Regards,
Néstor
