I am trying to connect to HBase standalone single cluster installed on my Ubuntu machine from Java Program. I followed the steps given in this blog. https://autofei.wordpress.com/2012/04/02/java-example-code-using-hbase-data-model-operations/
I am able to connect to HBase in EMR cluster when I run this code on AWS EC2 but not able to do it on my local. My hadoop is running and I am able to open hbase shell and scan 'storetable' is showing me some rows without any exception. It seems that the program is going in an infinite loop at line -
table = new HTable(HBaseConfig, "storetable");
because the message "HBase table created..." is never printed. There is no exception caught by the catch block. Please help me out.
I appreciate your help.
Code:
public void connectHBase()
{
System.out.println("Trying to establish HBase connection...");
HBaseConfig = HBaseConfiguration.create();
HBaseConfig.set("hbase.zookeeper.quorum", "localhost");
HBaseConfig.set("hbase.zookeeper.property.clientPort", "2181");
System.out.println("HBase Connection succeded...");
try
{
System.out.println("Creating HBase table...");
table = new HTable(HBaseConfig, "storetable");
System.out.println("HBase table created...");
}
catch(Exception e)
{
System.out.println("Some exception occured...");
e.printStackTrace();
}
}
Console Output:
Trying to establish HBase connection...
HBase Connection succeded...
Creating HBase table...
