Getting error when trying to connect to Phoenix from SQuirrel Client

Hi Friends,

I am not able to connect to the Phoenix from SQuirrel Client.

Versions used:

HDP 2.5.3.0, phoenix-4.7.0.2.5.3.0-37, Hbase 1.1.2, SQuirrel Client version 3.8.1

I have created 3 node cluster using Ambari Installation (ambari - 2.5.1) on AWS EC2 Instance. I am able to access the Phoenix layer by using sqlline.py.

I have followed the below link to configure SQuirrel.

https://community.hortonworks.com/articles/44350/setting-up-squirrel-and-phoenix-integration.html

I am able to create the Phoenix driver and alias successfully but when I try to connect (I am not using any userid or password) it gives me below error:

It looks like that the URL you specified may be wrong. Can you please check if the URL is correct?

The correct URL format is as follows:

jdbc:phoenix:<zookeeper quorum>:<zookeeper port>:<zookeeper znode parent>

You might not have specified correct zookeeper znode parent.

Hi @Anupam Kumar,

Could you please provide details whether cluster is kerberised(Secure) or un-kerberised(Unsecure)?

Thanks

@Toshihiro Suzuki

jdbc:phoenix:ec2-111-11-11-11.compute-1.amazonaws.com:2181/hbase-unsecure

I have put in this format.

Hi Friends,

I was putting the url incorrectly, ":" was missing from the url after the port number.

So the correct one is as below:

jdbc:phoenix:ec2-11-111-11-111.compute-1.amazonaws.com:2181:/hbase-unsecure

But now I am getting the below error:

Unexpected Error occurred attempting to open an SQL connection. class java.util.concurrent.TimeoutException: null

java.util.concurrent.TimeoutException at java.util.concurrent.FutureTask.get(FutureTask.java:205) at net.sourceforge.squirrel_sql.client.mainframe.action.OpenConnectionCommand.awaitConnection(OpenConnectionCommand.java:132) at net.sourceforge.squirrel_sql.client.mainframe.action.OpenConnectionCommand.access$100(OpenConnectionCommand.java:45) at net.sourceforge.squirrel_sql.client.mainframe.action.OpenConnectionCommand$2.run(OpenConnectionCommand.java:115) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748)

Please advice.
