Hadoop: ERROR conf.Configuration: error parsing conf core-site.xml

Question

Trying to set up a single-node system and am getting this error when running

hadoop jar HadoopWordCount.jar HadoopWordCount input.txt output

from the command line. and getting the following error. Input, output, and jar file are all in the same directory.

2018-08-30 10:43:23,266 ERROR conf.Configuration: error parsing conf core-site.xml
com.ctc.wstx.exc.WstxParsingException: Illegal to have multiple roots (start tag in epilog?).
 at [row,col,system-id]: [22,2,"file:/usr/local/Cellar/hadoop/3.1.1/libexec/etc/hadoop/core-site.xml"]

Runs perfectly in IntelliJ but assignment calls for the command line. Below is the core-site.xml file.

<?xml version="1.0" encoding="UTF-8"?>

Answer 1

property tag should be within configuration tag

<configuration> 
  <property> 
    <name>hadoop.tmp.dir</name> 
    <value>/usr/local/Cellar/hadoop/hdfs/tmp</value> 
    <description>A base for other temporary directories.</description> 
  </property> 
  <property>
    <name>fs.default.name</name>
    <value>hdfs://localhost:9000</value> 
  </property> 
</configuration>
