Solr Data Import Properties - Doesnt exist

Question

I am trying to do a delta import via the DIH in Solr. When I tried to do it I get this in my effort log:

INFO: Starting Delta Import

It doesnt work, but I think it is to do with this error:

WARNING: Unable to read: dataimport.properties

Apparently this file should be in my solr/conf directory but it isnt in this directory. Is this error stopping the DIH working and how do I go about creating this file. Any clues about why it isnt created by default would be interesting too.

Thank you!

Answer 1

I came across this issue and the fix is to make the conf directory writable. Or just make the dataimport.properties writable for all.

Answer 2

对我来说，使数据文件夹对所有人都可写解决了问题。
