Issue in starting Datafari 4.0.2 - Elasticsearch Fail

[Gonch Gonch]

Hey everyone,

I want to install Datafari 4.0.2 (datafari.deb) in an environnement Ubuntu 14.04 LTS 64bits.
I follow the instruction to install the datafari, but when I execute the following command:

 "bash start-datafari.sh",

I receive always an error message from elasticsearch and datafari will be not started.



Can anybody help me to resolve this problem, please ?

Best Regards,

Hi,

Sorry for the delay.

Did you solve your problem ? It seems that the ES port is not reachable. Do you have a firewall installed on the machine ?

Best regards,

Olivier

Hello,

No problem.

No I don't have resolve the problem yet.

Here, it is only a Linux Ubuntu 16.04 LTS machine that has no firewall installed.

Thanks for the reply.

Hello,

Could you tell me what are the resources of the machine especially CPU and RAM ?

It seems that ES could not start in time. It can be either a service running on the same port as I thought before but it seems that not. So it can be either that ElasticSearch had not enough time to start and the start script exits.

You can try to edit manually the file /opt/datafari/bin/start-datafari.sh :

Lines 68 to 72 there is a code block related to ELK :

# Configure ELK

echo "Configure ELK"

cd $ELASTICSEARCH_HOME/bin

sudo -E su datafari -p -c "bash elasticsearch -p $ELASTICSEARCH_PID_FILE" &

sleep 10

#Test if Elasticsearch is up, if not then exit

    curl -s --fail -XGET http://localhost:9200/ || { echo "Fail to reach Elasticsearch on localhost:9200"; echo "Please check your network connection and, in case a proxy is configured, that a proxy exception exists for 'localhost' and '127.0.0.1' !"; sudo -E su datafari -p -c "kill $(cat $ELASTICSEARCH_PID_FILE)"; exit 1; }   

First you can try to increase the sleep value to 120 so change sleep 10 to

sleep 120

If it still does not work, you can comment the line :

curl -s --fail -XGET http://localhost:9200/ || { echo "Fail to reach Elasticsearch on localhost:9200"; echo "Please check your network connection and, in case a proxy is configured, that a proxy exception exists for 'localhost' and '127.0.0.1' !"; sudo -E su datafari -p -c "kill $(cat $ELASTICSEARCH_PID_FILE)"; exit 1; }  

Just add # before the line :

#curl -s --fail -XGET http://localhost:9200/ || { echo "Fail to reach Elasticsearch on localhost:9200"; echo "Please check your network connection and, in case a proxy is configured, that a proxy exception exists for 'localhost' and '127.0.0.1' !"; sudo -E su datafari -p -c "kill $(cat $ELASTICSEARCH_PID_FILE)"; exit 1; }  

We added another check mechanism in Datafari 4.1 to avoid this problem and be more verbose in the log.

Let me know if it solves your issue meantime.

Thanks,
