Splunk index archiving to HDFS - throwing error "RollHandler - Could not find splunk_index"

[devender_splunk]

Though I can search index=digits from the search head, it's throwing the below message. Any clue on this?

"Could not find splunk_index=digits" warning is thrown when index digits does not exist. Since you can search index on SH, index does exist on SH.
Do you have distributed deployment with one or more indexers or indexer cluster. Archiving tries to archive data on SH and indexers. Most likely one of your indexer does not have index digits. This message could be coming from that indexer.
