11. Upgrade Oozie

To upgrade Oozie, run the following commands as the hadoop user:

Run ooziedb.cmd:

runas /user:hadoop "%OOZIE_HOME%\bin\ooziedb.cmd upgrade -run"

Replace your configuration: At each server and client, copy oozie\conf from the backup to the oozie\conf directory.
Replace the contents of /user/hdfs/share in HDFS. At the Oozie server host:
1. Back up the /user/hdfs/share folder in HDFS, and then delete it. If you have any custom files in this folder, back them up separately. Add them back after the share folder is updated.
```
mkdir c:\tmp\oozie_tmp 
runas /user:hadoop "cmd /c hdfs dfs -copyToLocal /user/hdfs/share c:\tmp\oozie_tmp\oozie_share_backup" 
runas /user:hadoop "cmd /c hdfs dfs -rm -r /user/hdfs/share"
```
2. Add the latest share libraries.
```
runas /user:hadoop "cmd /c hdfs dfs -copyFromLocal
%OOZIE_HOME%\share / user/hdfs/.
```
3. Start the Oozie service:
```
sc start oozie 
```
