[Koha] Elasticsearch 6 on Koha 20.05 - Reindexing Failure

[Craig Butosi]

Hi all,

Running Koha 20.05.06 on Ubuntu 18.04 with Elasticsearch 6.8.13:

I have 318 bib records; ~420,000 authority records

When running the following reindexing command (authorities only):

koha-elasticsearch --rebuild -d -v -a library2

I get the following error just before it commits 10,000 records:

[27771] Indexing authorities
[27771] 1000 records processed
[27771] 2000 records processed
[27771] 3000 records processed

[27771] 5000 records processed

Something went wrong rebuilding indexes for library2

At this point, I can confirm that 5000 authority records have been indexed,
but that's about 415,000 short :S

A couple other things:

   - My node is running when I curl localhost:9200. Top also shows ES
   running.
   - I have the ICU analysis plugin installed as well.


Never seen this error before. I was running ES 5.x but upgraded to 6.x
recently. Could the error above be related to 6.x? If so, can the errors be
resolved?

Any help would be much appreciated!
