Yep.. right. I realise that.
I did add the relevant JAVA_OPTS values for 17 compatibility. I also upgraded to 1.5.2 ES. What seemed to be part of the issue, some part of this reset the 'number of replicas' to 1 on the second node I updated. Weird.. but fixed. The Browser part of head doesn't work still... but that cold be a local issue...
However, in amonst all my installing an uninstalling, I now have a .watches index that cant be deleted, but the watcher index has been deleted.
So I now get a
curl -XGET 'http://awse-devmysqlproxy01:9200/_watcher/stats?pretty'
"error" : "LicenseExpiredException[license expired for feature [watcher]]",
"status" : 401
error. Has this been reported already. Seems that the plugin cant access the watcher index (because it isn't there)... but also cant install it, because the .watches index wont go either.
I am feeling a tad foolish... which is not normal for me
