Hi,

I have an issue when try to connect to external elasticsearch 6.8 with DMA, I'm using this DBConfiguration.xml config.

<?xml version="1.0"?>
<DataBases xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.skyline.be/config/db">
<DataBase active="true" local="true" type="Elasticsearch">
<ConnectString/>
<DBServer>35.175.118.112</DBServer>
<DSN/>
<DB></DB>
<UID>elastic</UID>
<PWD>changeme</PWD>
</DataBase>
</DataBases>

I get this error when restart DMA.

Hi Jose,

I was wondering, did you check first if you are able to query the Elasticsearch node from the server where the DMA is running? From a web browser (running from the server), can you perform the following query (based on your configuration):

http://35.175.118.112:9200/

This query should return information about the Elastic node. In case you are not able to retrieve any information, can you check if there is a firewall rule for port 9200?

Edit: Including a sample of DB.xml

<DataBases xmlns="http://www.skyline.be/config/db">
<DataBase active="true" local="true" type="Cassandra">
<ConnectString/>
<DBServer>localhost</DBServer>
<DSN/>
<DB>SLDMADB</DB>
<UID>root</UID>
<PWD>myPassword</PWD>
</DataBase>
<DataBase active="true" search="true" type="Elasticsearch">
<DBServer>10.11.12.13</DBServer>
<UID></UID>
<PWD></PWD>
</DataBase>
</DataBases>

Hi,

Yes, can access to 9200 port from my DMA, I think the issue is with db.xml config.
