I run a create_collection command like the following
create_collection [-c collectionName] [-n configName] [-d configDir] [-shards #] [-replicationFactor #] [-p port] [-V]
and I got the following error in the logs.

I am trying to create a standalone Solr with external zookeeper. I plan to replicate it later once I get this working. I used a custom config from a previous setup.
I solved the issue with this. The configs needed to be uploaded to Zookeeper using the following command
bin/solr zk upconfig -n <name for configset> -d <path to directory with configset>
After I did this it worked like a charm with no issues.
I was run 2 node in solr with single zookeeper to configure. I'll try to create a collection like location Its create successfully and then try to create second collection like contact. Its throw error.
Make API Call for create collection
curl -sS 'http://localhost:8983/solr/admin/collections?action=CREATE&name=contact&numShards=2&replicationFactor=2&maxShardsPerNode=2&collection.configName=conf_contact'

I am using Apache Flink(v1.10.0) to stream compute my RabbitMQ data, but when I config the check point data to store NFS file system like this:
env.setStateBackend(new FsStateBackend("nfs://28736435.boston.nas.amazonaws.com:/data/k8s/data/flink/checkpoint"));
give me this error:

The manual says it support NFS file system to store check points. where I am doing wrong with NFS file system config in Apache Flink?
You'll need to mount the NFS volume on every instance, and use the 'file' scheme, not 'nfs'.
Since you are running on AWS, it would be natural to use S3 for checkpointing. If you decide to do so, you should use flink-s3-fs-presto (s3p://) rather than flink-s3-fs-hadoop (s3a://), because the hadoop implementation has poor performance for checkpointing with Flink.
I recently deleted my Netbeans Cache folder (/appdata/local/netbeans/cache/) and my codenameone apps that make use of the native google maps plugin have been acting up. I get a runtime exception at startup. Below is the stacktrace.
I have removed cn1 plugin from NB, downloaded new copy of the native maps cn1lib, cleaned and built and i still get the same error... please help.

This started happening to one other user I'm aware of (but not to everyone surprisingly) as a result of the change to remove the maps in location manager. We had to remove them as Google became far too strict with maps key generation strategies.
We have a fix for this and will post it later on today or tomorrow morning.
I notice that after changing from solr 5.3 to 6.1, my code that creates an EmbeddedSolrServer (see below) will cause the following exception:
String solrHome = prop.getProperty(PROPERTY_FIELD_SOLR_HOME);
String solrCore = "anotherCore";
CoreContainer solrCores = new EmbeddedSolrServer(
Paths.get(solrHome), solrCore
).getCoreContainer();
EmbeddedSolrServer mycore=
new EmbeddedSolrServer(solrCores.getCore("mycore"));
The last line works ok with solr 5.3, but with 6.1, the following exception is generated. Any ideas please?

I'm having the same issue, but I imagine its because they removed that class from 6.1 (or sometime after 5.3). Removing the element from solrconfig.xml in the problematic core worked for me and should hopefully do the trick for you as well.
<!-- find this line in your solrconfig.xml and comment/remove it -->
<requestHandler name="/admin/"
class="solr.admin.AdminHandlers"/>
