Re: SolrCloud backup/restore

Thank you both for the clarification and proposals! This solrcloud_manager looks very promising. I'll try it out, the shared filesystem requirement is no issue for me. -- View this message in context: http://lucene.472066.n3.nabble.com/SolrCloud-backup-restore-tp4267954p4268197.html Sent

SolrCloud backup/restore

I've tested backup/restore successfully in a SolrCloud installation with a single node (no replicas). This has been achieved in https://issues.apache.org/jira/browse/SOLR-6637 Can you do something similar when more replicas are involved? What I'm looking for is a restore command that will restore

Re: XJoin, a way to use external data sources with Solr

Hi Tom, Thanks for clarifying the purpose of XJoin, makes sense now. Hope it makes it into Solr's main branch, this could prove useful! For the time being PostFilter covers my needs. -- View this message in context:

Re: XJoin, a way to use external data sources with Solr

Hi Charlie, This looks like an interesting feature, but I have a couple of questions before giving it a try. I had similar needs - filtering results based on information outside of the queried Solr collection - and I went down the post-filtering path. More specifically I've implemented a

Single-sharded SolrCloud vs Lucene indexing speed

I'm conducting some indexing experiments in SolrCloud and I want to confirm my conclusions and ask for suggestions on how to improve performance. My setup includes a single-sharded collection with 1 additional replica in SolrCloud 5.3.1. I'm using SolrJ and the indexing speed refers to the actual

Re: Index directory containing only segments.gen

Erick Erickson wrote OK, I think this is the root of your problem: bq: Everything was setup using the - now deprecated - tags cores and core inside solr.xml. There are a bunch of ways this could go wrong. I'm pretty sure you have something that would take quite a while to

Re: Index directory containing only segments.gen

Well, I don't know If I'm being helpful but here goes. My clusterstate.json actually has no leader for the shard in question. I have 2 nodes as recovery_failed and one as down. No leaders there. I've not used core admin or collections api to create anything. Everything was setup using the - now

Re: Index directory containing only segments.gen

From the logs I've got one instance failing as described in my first comment and the other two failing during PeerSync recovery when trying to communicate with the server that was missing the segments_* files. The exception follows org.apache.solr.client.solrj.SolrServerException: IOException

Index directory containing only segments.gen

I'm using SolrCloud 4.10.3 and the current setup is simple using 3 nodes with 1 shard. After a rolling restart of the Solr cluster I've ended up with 2 failing nodes reporting the following org.apache.solr.servlet.SolrDispatchFilter null:org.apache.solr.common.SolrException: SolrCore 'core' is

Re: PostingsHighlighter highlighted snippet size (fragsize)

It seems that a solution has been found. PostingsHighlighter uses by default Java's SENTENCE BreakIterator so it breaks the snippets into fragments per sentence. In my text_en analysis chain though I was using a filter that lowercases input and this seems to mess with the logic of SENTENCE

PostingsHighlighter highlighted snippet size (fragsize)

Hi all, I'm using SolrCloud 4.10.0 and trying to incorporate PostingsSolrHighlighter. One issue that I'm having is that I cannot have the functionality of hl.fragsize in PostingsSolrHighlighter. How can I limit the size of the highlighted text? I get highlighted results but their snippet size

Re: SolrCloud shard leader elections - Altering zookeeper sequence numbers

Daniel Collins wrote Is it important where your leader is? If you just want to minimize leadership changes during rolling re-start, then you could restart in the opposite order (S3, S2, S1). That would give only 1 transition, but the end result would be a leader on S2 instead of S1 (not sure

SolrCloud shard leader elections - Altering zookeeper sequence numbers

SolrCloud uses ZooKeeper sequence flags to keep track of the order in which nodes register themselves as leader candidates. The node with the lowest sequence number wins as leader of the shard. What I'm trying to do is to keep the leader re-assignments to the minimum during a rolling restart. In

Re: SolrCloud use of min_rf through SolrJ

In case anyone else runs into this, I've managed to make it work. I didn't notice in the ticket discussion that the specific feature is enabled when min_rf =2, I was setting min_rf=1. It goes without saying that you should also have at least 2 replicas in your SolrCloud configuration. The actual

SolrCloud use of min_rf through SolrJ

Hi all, I'm trying to make use of the min_rf (minimum replication factor) feature described in https://issues.apache.org/jira/browse/SOLR-5468. According to the ticket, all that is needed is to pass min_rf param into the update request and get back the rf param from the response or even easier
