[Koha] when will koha master work with elastic search 5.X

[David Holoshka]

Hi,

Thank you for your prompt replies.  We have tried reseting the mappings 
(yesterday was the 2nd time we tried) and rebuilt the ES indexes with 
similar results.  Now that I know that koha should work with ES 5 I can 
re check our configuration.  We have been using stuff from the koha 
unstable main and the koha nightly as per instructions: 
https://wiki.koha-community.org/wiki/Elasticsearch  .  I will try to 
rebuild the indexes with out using these repositories as I see that 
apt-get complains of some dependency issues.

Our system is:

Debian,

Koha cloned from master into /usr/local/koha using git

Mysql

ES 5.3  (it seems to be working fine) on oracle java 8 ( I could not 
find the open jdk 8 on the debian package list).

Marc 21

All perl catmandu modules are the latest from cpanm.


Best Regards,

Dave
