Found the problem. It is mysql version mismatched.

When your first post titled "Ambari-server start error" was caught by the spam filter, you created a second post with the same content. I approved one of them so we didn't have duplicate questions on the board. I am unsure why your posts were flagged as spam.

Hi Geoffrey, I have 4 data nodes and no snapshots set. Here are the output from the commands hdfs@msl-dpe-perf88:/$ hdfs dfs -df -h Filesystem Size Used Available Use% hdfs://msl-dpe-perf88.msl.lab:8020 28.2 T 27.1 T 0 96% hdfs@msl-dpe-perf88:/$ hdfs lsSnapshottableDir hdfs@msl-dpe-perf88:/$

@Harry Li It's paramount that you first go through this check list to prepare your new host to join the cluster. This is to avoid some frustrating errors especially having nonworking nodes in a cluster This document with screenshots for adding a data node to an existing HDP cluster looks good because the process is straightforward provided you followed the prerequisites.

@Harry Li Please try this to verify your JDBC driver version: On Ambari Server Host: # mkdir /tmp/JDBC # cd /tmp/JDBC # cp -f /var/lib/ambari-server/resources/mysql-connector-java.jar /tmp/JDBC/ # jar xvf mysql-connector-java.jar . The grep the version: # grep 'Implementation-Versio' META-INF/MANIFEST.MF Implementation-Version: 8.0.11 # cat META-INF/services/java.sql.Driver com.mysql.cj.jdbc.Driver . So if your MySQL JDBC Driver version is correct (MySQL 5 JDBC Driver then you might be seeing something like following instead: # grep 'Implementation-Versio' META-INF/MANIFEST.MF Implementation-Version: 5.1.25-SNAPSHOT # cat META-INF/services/java.sql.Driver com.mysql.jdbc.Driver . MySQL connector 5.1 download link: https://dev.mysql.com/downloads/connector/j/5.1.html

@Harry Li It looks like a Symlink issue. Looks like due to some reason the symlink is not created properly. The "lib" should be actually here # ls -l /usr/hdp/2.6.5.0-292/slider/lib/ . The "/usr/hdp/current/slider-client" path should be ideally a symlink something like following: # ls -l /usr/hdp/current/slider-client lrwxrwxrwx. 1 root root 27 Jun 28 22:44 /usr/hdp/current/slider-client -> /usr/hdp/2.6.5.0-292/slider NOTE: here the version "2.6.5.0-292" might be different based on your Stack version. So please change the version accordingly. . So you might want to create a symlink on your own. First if you have "slider-client" as a Directory or as a Symlink? # ls -ld /usr/hdp/current/slider-client lrwxrwxrwx. 1 root root 27 Jun 28 22:44 /usr/hdp/current/slider-client -> /usr/hdp/2.6.5.0-292/slider If you find that "/usr/hdp/current/slider-client" is a directory then move it. # mv /usr/hdp/current/slider-client /usr/hdp/current/slider-client_OLD Then create a symlink instead like: # ln -s /usr/hdp/2.6.5.0-292/slider /usr/hdp/current/slider-client NOTE: here the version "2.6.5.0-292" might be different based on your Stack version. So please change the version accordingly. .
