Helen,
The possible cause is other similar software is installed on the nodes of the cluster and the software residue is not completely deleted.
Troubleshooting Methods
Check whether the libhadoop.so file of another version exists in /usr/lib64/ of each node. If the file exists, delete it and restart the Spark service.
Procedure
1. Use PuTTY to log in to each node as user root.
2. Run the following commands to go to /usr/lib64/ and check whether the libhadoop.so file exists:
cd /usr/lib64
find libhadoop*
If the following information is displayed, the file exists:
libhadoop.so
libhadoop.so.1.0.0
3. Run the following command to delete the file:
rm -f libhadoop.so.1.0.0
rm -f libhadoop.so
4. Restart the Spark service. The fault is rectified.
Hope this helps!
