Apache Atlas Service unavailable?

[#1]

I am using Apache Atlas 1.0.0, after successful compilation, I try to start Atlas server using ./distro/target/apache-atlas-1.0.0-SNAPSHOT-bin/apache-atlas-1.0.0-SNAPSHOT/bin/atlas_start.py.

And it shows - ------------------------

starting atlas on host localhost

starting atlas on port 21000

Apache Atlas Server started!!!

------------------------------------------------

While using localhost:21000 in browser, it gives Error 503 : Service unavailable. Could anyone please suggest me, what should I do start the service.

And here is my Error log -

log4j:WARN No such property [maxFileSize] in org.apache.log4j.PatternLayout. log4j:WARN No such property [maxBackupIndex] in org.apache.log4j.PatternLayout. log4j:WARN No such property [maxFileSize] in org.apache.log4j.PatternLayout. log4j:WARN No such property [maxBackupIndex] in org.apache.log4j.PatternLayout. log4j:WARN No such property [maxFileSize] in org.apache.log4j.PatternLayout.

@manoj kumar,

org.apache.atlas.Atlas.main(Atlas.java:133) Caused by: java.net.BindException: Address already in use at

This means that the port is already occupied. Kill the process and restart again.

# netstat -tupln | grep 21000 
sample output :tcp6       0      0 :::21000                :::*                    LISTEN      28861/java
# kill -9 <pid>
ie. kill -9 28861

Thanks,

Hi @Aditya,

I killed the process, but issue not resolved. So, I reinstall Atlas project from the begining.

export MAVEN_OPTS="-Xmx1536m -XX:MaxPermSize=512m"

mvn clean install -DskipTests > log.txt

And then comes this error :-

/home/kafka/atlas/intg/src/main/java/org/apache/atlas/type/AtlasTypeUtil.java:437:84: unexpected token: > /home/kafka/atlas/repository/src/main/java/org/apache/atlas/discovery/EntityLineageService.java:133:28: expecting SEMI, found ',' log4j:WARN No such property [maxFileSize] in org.apache.log4j.PatternLayout. log4j:WARN No such property [maxBackupIndex] in org.apache.log4j.PatternLayout. log4j:WARN No such property [maxFileSize] in org.apache.log4j.PatternLayout. log4j:WARN No such property [maxBackupIndex] in org.apache.log4j.PatternLayout. log4j:WARN No such property [maxFileSize] in org.apache.log4j.PatternLayout.

Could you please look at this, and tell me what's going wrong here?

I am using linux 14.04 for Apache Atlas installation.

First I installed zookeeper, Apache Kafka.

and then performed following steps :

git clone https://github.com/apache/atlas.git"

export MAVEN_OPTS="-Xmx1536m -XX:MaxPermSize=512m"

sudo env "PATH=$PATH" mvn clean install -DskipTests

sudo env "PATH=$PATH" mvn clean package -DskipTests -Pdist,embedded-hbase-solr

After successfully installed, I run - sudo ./distro/target/apache-atlas-1.0.0-SNAPSHOT-bin/apache-atlas-1.0.0-SNAPSHOT/bin/atlas_start.py

then I go to brower and type : localhost:21000

it is not responding, says - service unavailable.

Please some one help me, what to do?

Thanks,

Manoj
