Wrong Zookeeper Client Information listed in Eclipse Java Program

[#1]

The below environment variables are wrong and seem to be from my local machine. I would expect Zookeeper to list the variables from my Sandbox on VirtualBox

2016-05-31 16:04:05,796 INFO [main] zookeeper.ZooKeeper: Client environment:zookeeper.version=3.4.6-1569965, built on 02/20/2014 09:09 GMT

all these value are getting picked up from your env variable http://grepcode.com/file/repo1.maven.org/maven2/org.apache.zookeeper/zookeeper/3.3.1/org/apache/zook...

please check your env variable

[#3]

How would I ensure it picks up the values from my VM.

[#4]

is there any zk client is running on your local machine which is trying to connect to zk-server running on vm?

[#5]

No. There is not zk client running on my local machine. I think my java program fails to connect to zookeper. I get the below error as well

@Daniel Buraimo

Are you trying to connect to hbase cluster ?

In your pom.xml, you should have dependency similar to the following:

[INFO] | +- org.apache.zookeeper:zookeeper:jar:3.4.6:compile

In your hbase-site.xml, the following two config parameters should have the correct values:

<property> <name>hbase.zookeeper.quorum</name>

</property>

<property> <name>zookeeper.znode.parent</name> <value>/hbase-unsecure</value> </property>

[#7]

Yes I'm trying to connect to an hbase cluster to perform CRUD oeprations on tables. My java program currently looks like this

Configuration conf = HBaseConfiguration.create();

try { HBaseAdmin.checkHBaseAvailable(conf);

}

catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

HBase Version	1.1.2.2.4.0.0-169, revision=61dfb2b344f424a11f93b3f086eab815c1eb0b6a
ZooKeeper Client Version	3.4.6-169, revision=-1
Zookeeper Quorum	sandbox.hortonworks.com:2181
Zookeeper Base Path	/hbase-unsecure
Hadoop Version	2.7.1.2.4.0.0-169, revision=26104d8ac833884c8776473823007f176854f2eb

All information gotten from Ambari Dashboard. The hbase-site xml were also downloaded from the Ambari dashboard. I'm currently using hbase-1.1.5 bin version jars in my local java project. I also had to set a local hadoop home directory in vm arguments because I got the below error

2016-06-01 10:12:17,088 ERROR [main] util.Shell: Failed to locate the winutils binary in the hadoop binary path java.io.IOException: Could not locate executable null\bin\winutils.exe in the Hadoop binaries.

The hbase-site xml didn't seem to be on your classpath - that was why 0:0:0:0:0:0:0:1:2181 appeared in the log.

Once you put hbase-site.xml on classpath, you should be able to connect.

[#9]

I've put the hbase-site.xml in the classpath. I get an updated log which I've atatchederrorlog.txt

Thank you for your help

[#10]

I also added the following to my local windows host file

127.0.0.1 localhost

10.0.2.15 sandbox sandbox.hortonworks.com
