• Edit the MCS URL, and retry logging in. For example, change the boldface characters in the following URL:

  https;//<host-name>:8443/app/mcs/#/app/overview

  To this:

  https;//<host-name>:8443/app/dfui

• Try signing in as a user who has fabric-level login permission.
• Dismiss the MCS page, clear your browser cache, and retry signing in.

1. Download the libssl1.1 package:

   wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.0g-2ubuntu4_amd64.deb

2. Use the following command to install the package:

   sudo dpkg -i libssl1.1_1.1.0g-2ubuntu4_amd64.deb

# cat /etc/environment
export http_proxy=http://<proxy_server_hostname_or_IP>:<proxy_port>
export https_proxy=http://<proxy_server_hostname_or_IP>:<proxy_port>
export HTTP_PROXY=http://<proxy_server_hostname_or_IP>:<proxy_port>
export HTTPS_PROXY=http://<proxy_server_hostname_or_IP>:<proxy_port>

1. Update the EXPORT section of /opt/mapr/conf/nfs4server.conf as follows:

   EXPORT
   {
     # Export Id (mandatory, each EXPORT must have a unique Export_Id)
     Export_Id = 30;
   
     # Exported path (mandatory)
     Path = /mapr/clustername; <-- here instead of mapr please use /mapr/clustername
   
     # Pseudo Path (required for NFS v4)
     Pseudo = /mapr;
   
     Squash = No_Root_Squash;
   
     # Required for access (default is None)
     # Could use CLIENT blocks instead
     Access_Type = RW;
   
     # Security type (krb5,krb5i,krb5p)
     SecType = sys;
   
     # Exporting FSAL
     FSAL {
       Name = MAPR;
     }
   
     #SuperUser_Uid = 0;
   }

   For more information about the /opt/mapr/conf/nfs4server.conf file, see Configuring NFSv4 Server.
2. Restart the NFSv4 server:

   maprcli node services -nodes <node names> -nfs4 restart

   For more information about starting or restarting NFSv4, see Starting, Stopping, and Restarting HPE Ezmeral Data Fabric NFSv4.

1. Identify the new external IP address for each cloud instance.
2. On each cloud instance:
   1. Log on as a sudo user.
   2. Update the certificate using the following manageSSLKeys.sh command:

      /opt/mapr/server/manageSSLKeys.sh createusercert -u moss -ug mapr:mapr -k <ssl_keystore_password> -p <ssl_truststore_password> -ips "<new external ip of the instance>" -a moss -w

   3. Restart the MOSS service:

      maprcli node services -nodes 'hostname -f' -name s3server -action restart -json

   NOTE You can obtain the ssl_keystore_password and ssl_truststore_password from the node where the configure.sh -secure -genkeys command was issued. In the /opt/mapr/conf/store-passwords.txt file, the passwords are listed under keys as ssl.server.keystore.keypassword and ssl.server.truststore.password.

   Use the following commands to ensure correct file ownership:

   chown mapr:mapr /opt/mapr/conf/ssl_usertruststore.p12
   chmod 0444 /opt/mapr/conf/ssl_usertruststore.p12"
   chown mapr:mapr /opt/mapr/conf/ssl_userkeystore.p12
   chmod 0400 /opt/mapr/conf/ssl_userkeystore.p12"

• http.proxy=<proxyServer>:<proxyPort>
• https.proxy=<proxyServer>:<proxyPort>

• The existing password is mapr123 (the default value) when the EEP upgrade is initiated.
• You upgrade the cluster first to release 6.2.0 and then subsequently to release 7.x.x.

• Creates a subdirectory to preserve the original .xml files. This subdirectory has the same name as the original Hadoop directory and a timestamp suffix (for example, hadoop-2.7.0.20210324131839.GA).
• Creates a subdirectory for the new Hadoop version (hadoop-2.7.6).
• Deletes the original hadoop-2.7.0 directory.

1. Create a file named prior_hadoop_dir that contains the Hadoop directory path. For example:

   # cat /opt/mapr/hadoop/prior_hadoop_dir
   /opt/mapr/hadoop/hadoop-2.7.0.20210324131839.GA

   If multiple directories are present, specify the directory with the most recent timestamp.
2. Run the configure.sh -R command as instructed to complete the EEP upgrade.

• Initiate the upgrade from the Data Fabric UI URL provided by the seed node when the fabric was created. This URL uses the API server node with the running installer service.
• If you must use an API server node other than the primary installer host:
  1. Copy the .pem file from the /infrastructure/terraform/ directory of the primary installer host to the /tmp directory of the secondary installer host where you want to initiate the upgrade.
  2. Restart the installer service on the secondary installer host:

     sudo service mapr-installer restart

  3. Initiate the upgrade as described in Upgrading a Data Fabric.
