Configure Custom User ID for FSAnalytics

In Pulse 4.1.8, if the FSAnalytics connector uses a user ID other than the default 1000:1000, it may fail with the following exception:

java.io.IOException: Invalid UID, could not determine effective user

Resolution

1. Navigate to the users configuration directory:

cd /data01/acceldata/config/users

2. Create copies of the existing passwd and group files:

cp passwd passwd_fs
cp group group_fs

3. Edit passwd_fs and group_fs to configure the required user ID and group ID. For example, for UID and GID 1008:
   passwd_fs

hdfs:x:1008:1008::/nonexistent:/bin/bash

4. group_fs

hdfs:x:1008:

5. Update the file ownership:

chown 1008:1008 /data01/acceldata/config/users/passwd_fs /data01/acceldata/config/users/group_fs

6. Navigate to the add-on configuration directory:

cd /data01/acceldata/config/docker/addons

7. Edit ad-fsanalyticsv2-connector.yml and add the following volume mounts under the existing volumes section:

volumes:
  # Retain existing volume mounts
  - ./config/users/passwd_fs:/etc/passwd
  - ./config/users/group_fs:/etc/group

8. Restart the ad-fsanalytics_connector service to apply the changes.
