Hi, I've tried to connect hadoop, spark, and Zeppelin, and I confirmed that hadoop and spark server is working well. But I can't connect to Zeppelin server. This is a log of zeppelin:

---------------------------------
And this is the code I changed in zeppelin-site.xml.template(in default, it didn't have zeppelin-site.xml)
<property>
<name>zeppelin.server.addr</name>
<value>127.0.0.1</value>
<description>Server binding address</description>
</property>
<property>
<name>zeppelin.server.port</name>
<value>9999</value>
<description>Server port.</description>
</property
------------------------------------------
And this is the code I inserted in zeppelin-env.sh.template(also, no zeppelin-env.sh)
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export MASTER=spark://localhost:7077
export ZEPPELIN_MEM="-Xms1g -Xmx8g -XX:MaxPermSize=1g"

export SPARK_HOME=/home/nahyeon/apps/spark
export HADOOP_CONF_DIR=/home/nahyeon/hdoop/hadoop-3.3.4/etc/hadoop
export PYSPARK_PYTHON=python3
export PYTHONPATH=python3
export ZEPPELIN_PORT=9999
-----------------------------------
**paths of ~/.bashrc are:
export ZEPPELIN_HOME=/home/nahyeon/apps/zeppelin
export PATH=$PATH:$ZEPPELIN_HOME/bin
It seems like although I chose the port number which is different from spark's default port number(8080), it doesn't apply. And maybe it's because it couldn't find XML configuration, according to the first line of the log above. But I'm not sure I understood well, and I have no idea how to fix it. Could anybody help me?
