Hey there!
Log in to the node where the original malfunctioning ZooKeeper instance resides and run the following command to check the directory.
ls -l /srv/BigData/zookeeper/version-2/.
If the directory is not blank, the instance has been restored.
Example:
-rw------- 1 omm wheel 1 Mar 5 18:24 acceptedEpoch
-rw------- 1 omm wheel 1 Mar 5 18:24 currentEpoch
-rw------- 1 omm wheel 67108880 Mar 5 18:31 log.600000001
-rw------- 1 omm wheel 873 Feb 27 02:47 snapshot.50000000d
-rw------- 1 omm wheel 665 Mar 5 18:13 snapshot.60000001d
-rw------- 1 omm wheel 849 Mar 5 18:24 snapshot.70000000c
After the ZooKeeper instance has been restored, run the following command to delete the backup file:
rm -rf /srv/BigData/zookeeper/version-2-bk
