Cause of error reporting: this error is caused by the failure to connect to the corresponding spark and other related service parsers. If the spark and Hadoop services run normally, it is the cause of version incompatibility.
Solution
Replace with a compatible Zeppelin version.

Caused by: java.io.IOException: Fail to launch interpreter process:
Apache Zeppelin requires either Java 8 update 151 or newer
Solution
Step 1: upgrade JDK to JDK1.8
Step 2: modify the Java of Hadoop and other services
Step 3: modify the Java of zeppelin-env.sh
Step 4: modify the JDK path in the common.sh file in the bin directory of Zeppelin (important!!!)
function check_java_version() {
//Modify JAVA PATH to: /opt/modules/jdk1.8.0_202
java_ver_output=$("${JAVA:-/opt/modules/jdk1.8.0_202}" -version 2>&1)
jvmver=$(echo "$java_ver_output" | grep '[openjdk|java] version' | awk -F'"' 'NR==1 {print $2}' | cut -d\- -f1)
JVM_VERSION=$(echo "$jvmver"|sed -e 's|^\([0-9][0-9]*\)\..*$|\1|')
if [ "$JVM_VERSION" = "1" ]; then
JVM_VERSION=$(echo "$jvmver"|sed -e 's|^1\.\([0-9][0-9]*\)\..*$|\1|')
fi
if [ "$JVM_VERSION" -lt 8 ] || { [ "$JVM_VERSION" -eq 8 ] && [ "${jvmver#*_}" -lt 151 ]; } ; then
echo "Apache Zeppelin requires either Java 8 update 151 or newer"
exit 1;

Problem Description: error 503 is reported on the page after Zeppelin is started
Solution:
You need to modify the directory permissions and attribution of webapp
drwxrwxr-x 3 hadoop hadoop 4096 Sep 9 11:23 webapps
chmod 755 webapps
chown -R hadoop:hadoop webapps/After modification, restart Zeppelin
[hadoop@10 /usr/local/service/zeppelin-0.9.0/bin]$ ./zeppelin-daemon.sh restart
Please specify HADOOP_CONF_DIR if USE_HADOOP is true
Zeppelin stop [ OK ]
Zeppelin start [ OK ]
[hadoop@10 /usr/local/service/zeppelin-0.9.0/bin]$web UI
