All solr cores in a solr server are down. Cannot find anything from log.

We have a 3 node solrcloud. Each solr collection has only 1 shard and 1 replica. When we restart the 3 solr nodes, we found all the cores in one solr node are at down state and not changed to other state. The solr node is shown in /live_nodes in zookeeper. After restarting all the zk server and

Hi George, Thank you for getting back to me. I am using Solr 6. I need to use coreContainer because I have created a CoreAdminHandler extension. Thanks, Fabrizio On Sun, Sep 11, 2016 at 6:42 PM, Georg Sorst wrote: > Hi Fabrizio, > > which Solr version are you using?

[Solr facet distinct count] Benchmark and implementation details

Hi gents, was taking a look to the ways to calculate distinct count per facet. Reading through Yonik blogs [1] it seems quite safe to assume the " unique(field)" is the approach to go. Do we have any benchmark or details about the implementation ? Because as per Yonik blog it is faster than

Unable to connect to correct port in solr 6.2.0

HI All, I am trying to setup the solr in Redhat Linux, using the install_solr_service.sh script of solr.6.2.0 tgz. The script runs and starts the solr on port 8983 even when the port is specifically specified as 2016. /root/install_solr_service.sh solr-6.2.0.tgz -i /opt -d /var/solr -u root

JNDI settings

I am using Solr 5.5 and wanting to add JNDI settings to Solr (for data import). I'm new to Solr Cloud setup (previously I was running Solr running as a custom bundled war) so I can't figure where to put the JNDI settings with user/pass themselves. I don't want to add it to jetty.xml because

Re: Unable to connect to correct port in solr 6.2.0

I just tried this out on ubuntu (sorry I don't have access to a red hat system) and it works fine. One thing that you have to take care of is that if you install the service on the default 8983 port then, trying to upgrade with the same tar to a different port does not work. So please ensure that

Re: Unable to connect to correct port in solr 6.2.0

Jan - the issue you are hitting is Docker and /proc/version is getting the underlying OS kernel and not what you would expect from the Docker container. The errors for update-rc.d and service are because the docker image you are using is trimmed down. Kevin Risden On Mon, Sep 12, 2016 at 3:19

Miserable Experience Using Solr. Again.

Hi, I have been on this list for some time because I know that any time I try to do anything related to Solr I’m going to have to spend hours on it, wondering why everything has to be so awful, and I just want somewhere to provide feedback with the dim hope that the product might improve one

For what it's worth - I found enough frustration upgrading that I decided to "upgrade by replacement" Now, I suppose if you've got a huge dataset to re-index that could be a problem, but just in case an option like that helps you, I'll suggest this. 1. Install 6.x on a new machine using the

Solr Cloud: Higher search latency with two nodes vs one node

I've been testing Solr Cloud 6.1.0 with two servers, and getting somewhat disappointing query latency. I'm comparing the latency with the same tests, running DSE in place of Solr Cloud. It's surprising, because running the test just on my laptop (running a single instance of Solr), I get

Sure - ping me off the list and I'll send my text file docs. They're rough and (of course) focused on what I'm doing, but they just might relieve some of the pain. Caveat - all on Linux and command line - no Admin UI api's -- I like the feel of the command line so I use it. On Mon, Sep 12, 2016

Re: Miserable Experience ..... Again.

I agree with what Erik wrote and some of Aaron’s original post. I’m relatively new to the Solr system (yes, pun intended) having just started diving into it a little over a year ago. I was in the “envious” position of being the only person who wanted to learn it and support it after our

I'm currently working on upgrading Alfresco from Solr 6.0 to Solr 6.2. Should be easy. Think again. Lucene analyzer changes between Solr 6.0 and Solr 6.2 and a new assert in ConjunctionDISI have caused days of work to perform this simple upgrade. Joel Bernstein http://joelsolr.blogspot.com/ On

Re: Miserable Experience Using Solr. Again.

I would also add that dealing with Java versions has always been a pain until you get used to the whole "JAVA HOME" thing, but that this isn't anything to do with SOLR per se - it's just part and parcel of dealing with open source software that uses Java... Big changes between major versions of

Re: Miserable Experience ..... Again.

Aaron - I for one sympathize. When I pause to think of the stacks upon stacks of technologies that something like Solr are built upon… my head spins and I feel for the folks coming to computer science these days and having the whole Java and Big Data stacks and all that goes along with that
