Apache Atlas 503 Error

Apache Atlas 503 Error

Expert Contributor

Hi

I am not using HDP. I built and installed apache atlas using the following link Atlas Installation. When I start Atlas using the atlas_start.py script the web UI gives the 503 error. I have checked the logs which are as follows:

Any suggestions how to resolve this issue?

Thanks

@Arsalan Siddiqi

From the exceptions it appears that the Atlas is having difficulty connecting to Kafka.

From the web UI exception, it appears to be a build problem.

Can you please confirm which profile have you used for build is it berlekeyDB & elasticSearch or is it hbase & solr.

@Ashutosh Mestry i used hbase & solr

Can you share some details on how you built/started atlas ? What env are you working on ?

i am running atlas on Ubuntu 16.4.... i followed the instructions on the following link:

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

Re: Apache Atlas 503 Error

Can check if Zookeeper is alive and accepting connections ?

I usually check using this command, assuming that the host is localhost and the Zookeeper port is 2181

telnet localhost 2181

@Ashutosh Mestry

i checked and zookeeper is running and accepting connections. Attached is the log file:atlas20170812-204645.txt

I am unable to proceed. Kindly help

@Arsalan Siddiqi

The root cause of the NullPointerException on the Zookeeper:

Caused by: java.lang.NullPointerException
	at org.apache.hadoop.hbase.zookeeper.ZooKeeperWatcher.getMetaReplicaNodes(ZooKeeperWatcher.java:395)
	at org.apache.hadoop.hbase.zookeeper.MetaTableLocator.blockUntilAvailable(MetaTableLocator.java:553)
	at org.apache.hadoop.hbase.client.ZooKeeperRegistry.getMetaRegionLocation(ZooKeeperRegistry.java:61)

.

It usually happens when the Zookeeper Parent is not defined properly. (i mean empty).

Please double check your Zookeeper URL.

Please check your "hbase-site.xml" location if it is present in the classpath and has correct ZK url. The ZK URL should include the children of hbase znode.

Re: Apache Atlas 503 Error

@Arsalan Siddiqi

Please check if your "hbase-site.xml" file is present in the Atlas Classpath (conf) dir and the following properties inside your hbase-site.xml are correctly set.

hbase.zookeeper.quorum=zoo1,zoo2,zoo3
zookeeper.znode.parent=/what/ever<br>

.

If the "zookeeper.znode.parent" is not correctly set then it can cause "NullPointerException"

Following link described the details: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.5.6/bk_command-line-installation/content/config...

@Jay SenSharma I am not running atlas on HDP. I had a look into the conf dir. I have a hbase folder there. It has a hbase.site.xml template. i renamed the file. the file has the following contents:

<configuration>
  <property>
    <name>hbase.rootdir</name>
    <value>${url_prefix}${atlas_data}/hbase-root</value>
  </property>
  <property>
    <name>hbase.zookeeper.property.dataDir</name>
    <value>${atlas_data}/hbase-zookeeper-data</value>
  </property>
  <property>
    <name>hbase.master.info.port</name>
    <value>61510</value>
  </property>
  <property>
    <name>hbase.regionserver.info.port</name>
    <value>61530</value>
  </property>
  <property>
    <name>hbase.master.port</name>
    <value>61500</value>
  </property>
  <property>
    <name>hbase.regionserver.port</name>
    <value>61520</value>
  </property>	
<property>
<name>zookeeper.znode.parent</name>
<value>/hbase-unsecure</value>
</property>
	
</configuration>

I restarted atlas but I get the same exception. Also I have installed zookeeper and it is running on port 2181. Also i am running things locally on my laptop. using default configurations in application properties:
