Hello, If you not modified anything but still you can't access HDFS from hue which was working earlier then you should try this solution i.e Restart httpfs service

This answer may not help the person who asked but still wanted to post it as somebody could benefit from it. There are multiple ways to solve this that explained in this artilce. https://sparkbyexamples.com/hadoop/hadoop-unable-to-load-native-hadoop-library-for-your-platform-warning/ For me, setting the below environments solved my problem. export LD_LIBRARY_PATH=$HADOOP_HOME/lib/native # (OR) If you have hadoop library installed at /usr/lib/ export LD_LIBRARY_PATH=/usr/lib/hadoop/lib/native Thanks

STEP 1: Get certificate from ambari-server echo | openssl s_client -showcerts -connect <AMBARI_HOst>:<AMBARI_HTTPs_PORT> 2>&1 | sed --quiet '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/ambari_certificate.cr STEP 2: Get path of ambari trustore and truststore password from Ambari properties cat /etc/ambari-server/conf/ambari.properties |grep truststore As per your ambari.properties below is the path and password :- ssl.trustStore.password=refer from ambari.property file ssl.trustStore.path=/etc/ambari-server/conf/ambari-server-truststore STEP 3: keytool -importcert -file /tmp/ambari_certificate.crt -keystore <keystore-path> STEP 4: ambari-server restart

To resolve the issue, import the Ambari certificates to the Ambari truststore. To import the Ambari certificates, do the following: STEP 1: Get certificate from ambari-server echo | openssl s_client -showcerts -connect <AMBARI_HOst>:<AMBARI_HTTPs_PORT> 2>&1 | sed --quiet '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/ambari_certificate.cr STEP 2: Get path of ambari trustore and truststore password from Ambari properties cat /etc/ambari-server/conf/ambari.properties |grep truststore As per your ambari.properties below is the path and password :- ssl.trustStore.password=refer from ambari.property file ssl.trustStore.path=/etc/ambari-server/conf/ambari-server-truststore STEP 3: keytool -importcert -file /tmp/ambari_certificate.crt -keystore <keystore-path> STEP 4: ambari-server restart

Yes I did.. Is there a way I can check in MySql if the changes are applied. Thanks

@prakashpunj Please accept my first reply as the solution?

@prakashpunj By default it uses sqllite as Database (no password). However, you can try checking the following files for more details on the Superset host. # grep 'SUPERSET_DATABASE_PASSWORD' /etc/superset/conf/superset_config.py # grep 'SUPERSET_DATABASE_PASSWORD' /var/lib/ambari-agent/data/command-* . Via ambari Ui you can check Ambari UI --> Superset --> Configs --> 'SUPERSET META DATA STORAGE CONFIG' (tab) Search for "Superset Database password" section in the above page and verify if it is empty or password is set. .

Thanks @Jay Kumar SenSharma. Question: On other nodes, do we have to do anything after installing new version of JAVA. Just by putting the JAVA in the same path as Ambari-server, is that going to be ok..?

jsensharma · ‎07-16-2018

@Prakash Punj Was there any yum update command triggered or any rpm update which might have caused upgrade of pythin / jdk binaries? may be looking at the /var/log/yum.log or installation/update history can help in understanding what changed recently on the vm.
