Problems constructing a proper core-site.xml

1

I am trying to set up dist storage to a private (internal S3-like) object store but having problems constructing a proper core-site.xml file.

<?xml version="1.0"?>
<configuration>
   <property>
       <name>fs.dremioS3.impl</name>
       <description>The FileSystem implementation. Must be set to com.dremio.plugins.s3.store.S3FileSystem</description>
       <value>com.dremio.plugins.s3.store.S3FileSystem</value>
   </property>
   <property>
       <name>fs.s3a.access.key</name>
       <description>AWS access key ID.</description>
       <value>ABCDEFGHIJKLMNOP</value>
   </property>
   <property>
       <name>fs.s3a.secret.key</name>
       <description>AWS secret key.</description>
       <value>12344556788901234455678890</value>
   </property>
   <property>
       <name>fs.s3a.aws.credentials.provider</name>
       <description>The credential provider type.</description>
       <value>org.apache.hadoop.fs.s3a.SimpleAWSCredentialsProvider</value>
   </property>
   <property>
       <name>fs.s3a.endpoint</name>
       <value>test.objstore.domain.com</value>
   </property>
   <property>
       <name>fs.s3a.path.style.access</name>
       <value>true</value>
   </property>
   <property>
       <name>fs.s3a.signing-algorithm</name>
       <value>S3SignerType</value>
   </property>
   <property>
       <name>fs.s3a.paging.maximum</name>
       <value>999</value>
   </property>
</configuration>

And this is what I get when trying to start Dremio:

2020-03-10 18:25:34,643 [main] ERROR ROOT - Dremio is exiting. Failure while starting services.

Anyone have any advice as to what I could try to get this configured correctly?

This is what I have in dremio.conf:

paths: {
  # the local path for dremio to store data.
  local: ${DREMIO_HOME}"/data"

  # the distributed path Dremio data including job results, downloads, uploads, etc
  #dist: "pdfs://"${paths.local}"/pdfs"
  dist: "dremioS3://test.objstore.domain.com/dds/accel"
}

I should add that I am able to successfully connect to the bucket when set up as a data source within Dremio.

Well, looks like I had malformed xml with some extra whitespace on the first line. Dremio is able to start up now.
