Applying a Service Pack

Applying a Service Pack is completed without running the Upgrade Wizard.

To apply a service pack:

Log in to the Cloudera Manager Admin Console.
Ensure that you have completed the steps to add the Parcel URL for the service pack and have downloaded and distributed the parcel in Cloudera Manager. See Step 5: Access Parcels.
Click Parcels from the left menu.
Click Parcel Repositories & Network Settings.
Locate the row in the table that contains the new Cloudera Runtime parcel and click the Activate button.
Cloudera Manager displays the progress of the activation.
When the parcel is activated and complete for all hosts in the cluster, click the Actions menu next to the cluster name and select Post Cloudera Runtime Upgrade .
Restarting the cluster:
- With downtime on services: Click the Actions menu and select Restart.
  or
- Rolling Restart the cluster to avoid downtime on services: Click the Actions menu and select Rolling Restart.

The cluster now has the new service pack applied.

If a Ranger database patch is included in a minor version upgrade, such as CDP-7.1.7 SP2-CHF4+ or CDP-7.1.8 CHF5+ , you must apply patches to the Ranger and Ranger RMS database manually. Perform the following steps:

Stop the Ranger and Ranger RMS services.
Go to Cloudera Manager > Ranger > Actions.
In Actions, click Upgrade Ranger Database and apply patches, then click Confirm.
Restart Ranger and Ranger RMS services.

As a result, DB patches will be applied to the Ranger database. When RMS server is started, it will perform a full-sync as RMS tables will be truncated during this procedure.

Mapreduce and Tez framework archives

As a post-upgrade step, you must check that location in HDFS to ensure that it is the latest version, and run the following if it does not:

hdfs dfs -ls /user/yarn/mapreduce/mr-framework/

If only the old version's tar file exists there, such as:

/user/yarn/mapreduce/mr-framework/3.1.1.7.1.7.78-12-mr-framework.tar.gz

Then perform the following: Cloudera Manager > Yarn > Actions > Install YARN MapReduce Framework JARs.You can clear out the old tar file after this is done for keeping it clean.

Tez MR Framework JARs and Oozie Sharelib entities must be examined in the similar manner. Check that location in HDFS to ensure that it is the latest version, and run the following if it does not:

Cloudera Manager > Yarn > Actions > Install YARN MapReduce Framework JARs
Cloudera Manager > Tez > Actions > Upload Tez tar file to HDFS
Cloudera Manager > Oozie > Actions > Install Oozie ShareLib

Clear any old files out of these directories:

hdfs dfs -ls -R /user/yarn/mapreduce/mr-framework/

```
hdfs dfs -ls -R /user/tez/
```
```
hdfs dfs -ls /user/oozie/share/lib/
```
