Re: partial update in solr

[Zahra Aminolroaya]

Thanks Alex. I want to have a query for atomic update with solrj like below:

http://localhost:8983/solr/test4/update?preprocessor=atomic=set=set=set=true=%3Cadd%3E%3Cdoc%3E%3Cfield%20name=%22id%22%3E11%3C/field%3E%3Cfield%20name=%22text3%22%20update=%22set%22%3Ehi%3C/field%3E%3C/doc%3E%3C/add%3E


First, in solrj, I used "setfield" instead of "addfield" like
doc.setField("text3", "hi");


Then, I added ModifiableSolrParams :


ModifiableSolrParams add = new ModifiableSolrParams()
.add("processor", "atomic")
.add("atomic.text", "set")
.add("atomic.text2", "set")
.add("atomic.text3", "set")
.add(UpdateParams.COMMIT, "true")
.add("commit","true");

And then I updated my document:

req.setParams(add);
req.setAction( UpdateRequest.ACTION.COMMIT,false,false );
 req.add(docs);
 UpdateResponse rsp = req.process( server );



 However, I get "No such processor atomic"


As you see I set commit to true. What the problem is?

Re: partial update in solr

Thanks Alex. I try the following to set the atomic processor:

http://localhost:8983/solr/test4/update?processor=atomic=add

However, I get the following error:



400

org.apache.solr.common.SolrException

I read in

partial update in solr

[Zahra Aminolroaya]

Does Solr have a partial update like elastic?

Elastic will automatically merge new document with the existing one having
the same id. For example if the new document has a value for field that it
was previously null, it will add the value for that field.


However, based on what I found, partially update in solr could be applied
only by directly defining the updated field sth like below:

curl 'localhost:8983/solr/update?commit=true' -H
'Content-type:application/json' -d '[{"id":"1","price":{"set":100}}]'

I do not want to define the updated field for Solr by sth like "set". I want
Solr to automatically merge documents with same id instead of deleting the
previous document and inserting the new document.

Can Solr do that?

What would be the challenges that I will confront with as my schemaless

In solr 7, is commenting add-unknown-fields-to-the-schema the only

Re: using uuid for documents

[Zahra Aminolroaya]

Hello Alfonso,

I expected that we could use *uuid* updateRequestProcessorChain like below
for generating unique value for unique key:


 
uniqueKey 




However, I saw that you used *dedupe* updateRequestProcessorChain as below;

 
 
  true 
………

I wonder if we can use *UUIDUpdateProcessorFactory* class instead of
*SignatureUpdateProcessorFactory* class!

using uuid for documents

[Zahra Aminolroaya]

I have two questions about using uuid:

 In Solr refs, it is stated that the unique id could be of uuid type. I
found we can generate uuid when the doc id with uuid field type is null or
we it is generated by using
doc.addField("id", UUID.randomUUID().toString()) in solrj.

 1- Suppose my unique id type is string. Can I generate a uuid value from my
unique id string and insert it as a distinct uuid field in Solr?


 1- Suppose my unique id type is uuid. If I try to insert a random string
which is not in uuid format, I get the "invalid uuid" error. Is there anyway
to generate a correct uuid value in solr GUI similar to what solrj 
UUID.randomUUID().toString() generates?

Best,
Zahra

Error casting to PointField

[Zahra Aminolroaya]

We read that in Solr 7, Trie* fields are deprecated, so we decided to change
all of our Trie* fields to *pointtype Fields. 

Our unique key field type is long, and we changed our long field type
something like below;



We get the error uniqueKey field can not be configured to use a Points based
FieldType.


I think it is a bug. If lucene decides to deprecate the Trie* filed type, it
should also think of these kinds of errors.


What is the solution?

Error with plugin in Solrcloud

[Zahra Aminolroaya]

My plugin works correctly in Solr. Now I want to have my plugin in solrCloud
mode:

I have a main jar file named "norm" and I have other jar files that my
"norm" is dependent on them:
"lucene-analyzers-common-6.6.1","lucene-core-6.6.1","slf4j-api-1.7.7","solr-core-6.6.1".

With the help of config and blob API, I transferred my libraries to .system
collection:


 {
"id":"norm/1",
"md5":"a4e068a60fb654d77cdb5f7d017bc1ec",
"blobName":"norm",
"version":1,
"timestamp":"2018-07-04T06:07:36.799Z",
"size":3377,
   
"blob":"UEsDBAoAAAgAABBX2UwJAAQATUVUQS1JTkYv/soAAFBLAwQKAAAIAAAPV9lMWXZiSjsBA
…….}

and I add these run time libraries to my collection, so my
configoverlay.json is like this:

{
  "props":{"updateHandler":{"autoSoftCommit":{"maxTime":3000}}},
  "runtimeLib":{
"norm":{
  "name":"norm",
  "version":1},
"slf":{
  "name":"slf",
  "version":1},
"lucene":{
  "name":"lucene",
  "version":1},
"lucene-ana":{
  "name":"lucene-ana",
  "version":1},
"solr-core":{
  "name":"solr-core",
  "version":1}}}

I also added my filter to my field type:

 

  
  
  
 


  
  
  
  

  

however, I get class not found exception.

Is there anything else that I should do to have my plugin for solr cloud
mode?

However, I found that StrField (string) does not support specifying an

I want to have the same application of string. Do you think it is reasonable
to use  "text_general" field type with solr.KeywordTokenizerFactory filter
to have the same application? Do I lose any feature?

If I use text_general, it is not needed to truncate.

Re: Changing Leadership in SolrCloud

[Zahra Aminolroaya]

Dear Mr. Shalin,

Yes. I mean "state" in Cluster State API and UI.

Let me explain what happened previous days by detail:

Think I have Collection A distributed across node1 (the leader), node2 and
node 3. 

I used the following command to block node 1 solr and zookeeper ports from
being listend:
(the ports are 2888/3888/2181 and 4239)

firewall-cmd --remove-port=/tcp --permanent

node 1 state is still "active", and leader is "true" in response of Cluster
State API.

the Solr logs of node 1 is like below:


org.apache.solr.common.SolrException: ClusterState says we are the leader
(:4239/solr/collectionA_shard2_replica1), but locally we don't
think so. Request came from :4239/solr/collectionA_shard4_replica3/

node 2 error in solr logs is:

forwarding update to :4239/solr/collection A_shard5_replica1/
failed - retrying ... retries: 24 add{,id=121,commitWithin=1000}
params:update.chain=add-unknown-fields-to-the-schema=TOLEADER=node2:4239/solr/collection

rsp:503:org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException:

node 3 error in solr logs is like node 2 error.



Unforunately, today I found that my node 4 and node 5 from collection B and
C became down. The  logs errors were like below:

I think these errors are related to blocking the ports of node 1.

I wonder if you help me.

Thanks Shalin. our "zkClientTimeout" is 3, so the leader should be
changed by now; However, the previous leader is still active.

The leader status is active. My main question is that how I can change the
leader in SolrCloud.

Thanks Shawn for the reply. when I try to add a document to solr I get the
"no route to host" exception. this means that SolrCloud is aware of the
blocking ports; However, zookeeper does not automatically change the leader!
