Hi all,
I'm writing simple java program to connect to HBase.
Versions of software used
Hbase 0.96.0-hadoop2
Hadoop:hadoop-2.2.0.
I'm trying to connect from my windows 7 (32 bit)machine to oracle linux
machine (Details :VM, 64 bit).Note I have not installed ZooKeeper.
Any suggestion or comments will be of great help
Thanks
Here is the script...
*package* pack1;
*import* java.io.IOException;
*import* org.apache.hadoop.conf.Configuration;
*import* org.apache.hadoop.hbase.HBaseConfiguration;
*import* org.apache.hadoop.hbase.client.HTable;
*import* org.apache.hadoop.hbase.client.Put;
*import* org.apache.hadoop.hbase.util.Bytes;
*public* *class* testDB {
/**
* *@param* args
*/
*public* *static* *void* main(String[] args) {
*try* {
System.*out*.println("1 Before HBASE COnfiguration");
Configuration config = HBaseConfiguration.*create*();
config.clear();
System.*out*.println("2 Before HBASE COnfiguration");
config.set("hbase.master", "192.168.1.42:60010");
System.*out*.println("HBase is running!");
HTable table;
table = *new* HTable(config, "mytable");
System.*out*.println("Table mytable obtained ");
Put put = *new* Put(Bytes.*toBytes*("row1"));
put.add(Bytes.*toBytes*("colfam1"),Bytes.*toBytes*("qual1"
),Bytes.*toBytes*("val1"));
put.add(Bytes.*toBytes*("colfam1"),Bytes.*toBytes*("qual2"
),Bytes.*toBytes*("val2"));
table.put(put);
} *catch* (IOException e) {
e.printStackTrace();
}
}
}
Error message
1 Before HBASE COnfiguration
2 Before HBASE COnfiguration
HBase is running!
