Apache Atlas Started but with Errors and Warnings

[#1]

I have followed the following link to build and install Apache Atlas

Link: http://atlas.incubator.apache.org/InstallationSteps.html

And selected to install the embedded-hbase-solr profile, but when I started Atlas after installation it is showing me the following errors and warning.

I have also tried to see which version is running curl -v http://localhost:21000/api/atlas/admin/version but it is giving the following:

* Hostname was NOT found in DNS cache * Trying 127.0.0.1... * connect to 127.0.0.1 port 21000 failed: Connection refused * Failed to connect to localhost port 21000: Connection refused * Closing connection 0 curl: (7) Failed to connect to localhost port 21000: Connection refused

Kindly let me know how shall I proceed to ensure Altas is working in the correct order. Any help will be highly appreciated. Thanking you in anticipation.

Kind Regards

@Nixon Rodrigues the contents of the log file are too big to be posted here so I have just posted the beginning of the file for reference.

@Bilal Arshad

Not able to understand from the logs you provided, but suspect the error while connecting to hbase.

I build and run Atlas using mvn clean package -Pdist,embedded-hbase-solr -DskipTests

and have following env variable set in .bashrc profile

export MAVEN_OPTS="-Xmx1536m -XX:MaxPermSize=512m"
export MANAGE_LOCAL_SOLR=True
export MANAGE_LOCAL_HBASE=True

Can you add this env variable and try restarting Atlas.

[#5]

@Nixon Rodrigues I tried adding the env variables to .bashrc and started atlas. It is still giving me the following:

hduser@bilal-VirtualBox:~/atlas/distro/target/apache-atlas-0.8-incubating-SNAPSHOT-bin/apache-atlas-0.8-incubating-SNAPSHOT$ bin/atlas_start.py

Apache Atlas Server started!!!

@bilal Arshad,

You are not able to connect to 21000 port , it seems to be firewall issue.

please check firewall related settings

[#7]

@Nixon Rodrigues I have disabled the firewall for now to see if it works but it is still giving the following:

[#8]

@Bilal Arshad,

What is OS you are using, are you using VM ?

Please attach your conf/atlas-application.properties and logs/application.log

I am using Ubuntu 14.04 on a VM.
