I sometimes also do get null ranges when doing colletions/cores API
actions CREATE or/and UNLOAD, etc... In 4.4.0 that was not easily fixed
because zkCli had problems with "putfile" command, but in 4.5.0 it works
OK. All you have to do is "download" clusterstate.json from ZK ("get
/clusterstate.json"), fix ranges to appropriate values and upload the file
back to ZK with zkCli.
But why those null ranges happen at all is beyond me :)

Subject: Re: Regarding Solr Cloud issue...
I'm sorry I am not able to reproduce this issue.
I started 5 solr-4.4 instances.
I copied example directory into example1, example2, example3 and example4
cd example; java -Dbootstrap_confdir=./solr/collection1/conf
-Dcollection.configName=myconf -DzkRun -DnumShards=1 -jar start.jar
cd example1; java -Djetty.port=7574 -DzkHost=localhost:9983 -jar start.jar
cd example2; java -Djetty.port=7575 -DzkHost=localhost:9983 -jar start.jar
cd example3; java -Djetty.port=7576 -DzkHost=localhost:9983 -jar start.jar
cd example4; java -Djetty.port=7577 -DzkHost=localhost:9983 -jar start.jar
After that I invoked:
http://localhost:8983/solr/admin/collections?action=CREATE&name=mycollection51&numShards=5&replicationFactor=1
I can see all shards having non-null ranges in clusterstate.
