Hi,

I am getting the below log very frequently and I can't find more details 
about it.

ZKPropertiesWriter      Could not read DIH properties from 
/configs/<core_name>/dataimport.properties :class 
org.apache.zookeeper.KeeperException$NoNodeException

Details:

We have a Solr cluster containing 2 Solr nodes and 2 replica. There are 2 
servers where the nodes and replicas are deployed. So,

server1 has node1 & node2_replica
server2 has node2 & node1_replica.

In another server we have deployed a single instance of Zookeeper (I would 
consider it make a Zookeeper ensemble). 
All the servers are in AWS auto-scaling so if any one is down another one 
pops up and the Solr/Zookeeper gets installed in there.

We are creating Solr cores using the below API:
http://<hostname>/
admin/collections?action=CREATE&name=&numShards=&replicationFactor=&maxShardsPerNode=&collection.configName=&wt=json

We are feeding data into the Solr  cluster using a batch job using the 
POST API  http://<hostname>/solr/collection/update?commit=true&wt=json.
We do not use Data Import Handler to import data. But still we are getting 
the exception. 

In one post  I have read that partial import using DIH can cause the 
problem but I am not using DIH here.

While querying data using the below API no result is returning (previously 
it was returning data).
https://SolrHostname/solr/<core>/select?q=(Composition)&defType=edismax&qf=title^2
 
author impn source&rows=100&wt=json

It would be a great help if someone provide me a clue. Please let me know 
if more details are needed to analyze.


Thanks & Regards
Sumit Pal
