Looks like you might be running your ambari server With HTTPS and the configured ambari truststore file is somehow corrupted or changed. Can you please check if you are able to do a "keytool -list" on you ambari keystore & truststore to see if you are able to list it ?
# $JAVA_HOME/bin/keytool -list -v -keystore <AMBARI_JKS> -storepass <CLIENT_TRUSTSTORE_PASSWORD>
Something similar is discussed here: https://community.hortonworks.com/questions/91725/yarn-queue-manager-error.html
In general this error"Keystore was tampered with, or password was incorrect."indicates that
1. the storepassword that you have specified in the ambari is not correct2. may be somehow the store password is not written in ambari.properties properly (or there may be some extra padding in the file)
3. ambari might be pointing to some other store file. (ambari.properties can be checked to verify the same)
4. It is also possible when your "KeyPass" is different from "StorePass" in your keystore.
I will suggest if you can either try regenerating a new truststore and then perform the "ambari-server setup-security" as mentioned in the following article again.https://community.hortonworks.com/articles/39865/enabling-https-for-ambariserver-and-troubleshootin....
@Jay Kumar SenSharma Yes, running ambari server with HTTPS.
I guess truststore file is changed, or
because i don't have root privileges,
i am unable to do keytool -list,
I didn't perform the second check for the same reason, can run ambari-server restart, but it might affect to business.
Also thanks for links and support.
Can you copy the ambari keystore on "/tmp" directory where you will have the read permission on the keystore and then try to see if you are able to list the keystore keys to verify if the store Password that you are using is correct and if the keystore is correct.
# $JAVA_HOME/bin/keytool -list -v -keystore /tmp/<AMBARI_JKS> -storepass <CLIENT_TRUSTSTORE_PASSWORD>
