The fuseki configuration below sets up two services with a shared
dataset. The dataset has a lucene text index.
This configuration works on Fuseki 1.3.1. Fuseki 2.3.1 fails to start.
The log output is shown below. Looks like the lucene index may be
trying to grab a lock for the dataset twice.
If I change the second fuseki:dataset line to:
[[
fuseki:dataset <#ds> ;
]]
then it works on Fuseki 2.3.1 and Unexpectedly both services have
access to the text index, which doesn't seem right, thought suits me for
the moment as I need both services to have access to the index.
Is there some configuration change I need to make between Fuseki 1 and
Fuseki 2?
