Where is emrfs-site.xml?

Question

Where is emrfs-site.xml on the EMR master node?

Consistent view is disabled within the EMR UI but I am unable to find the configuration file to verify.

sudo find / -name emrfs-site.xml

yields

/var/aws/emr/bigtop-deploy/puppet/modules/emrfs/templates/emrfs-site.xml
/usr/share/aws/emr/emrfs/conf/emrfs-site.xml

Neither of which seem to be relevant.

This is the relevant one:

/usr/share/aws/emr/emrfs/conf/emrfs-site.xml

It seems to be a strange place, but the path to the config file is hardcoded in java code. You can verify this by logging the debug output of the root logger to the console:

export HADOOP_ROOT_LOGGER="DEBUG,console

If consistent view is enabled, the following should be in that file:

<property>
  <name>fs.s3.consistent</name>
  <value>true</value>
</property>
