Eric Pugh resolved SOLR-9789.
-----------------------------
Resolution: Won't Fix
We have removed zkcli. At this point, I think we either should recommend a
ZooKeeper native CLI tool, or we should reopen these tickets to target our
bin/solr zk tooling.
> ZkCLI throws NullPointerException if zkClient doesn't return data

> Key: SOLR-9789
> URL: https://issues.apache.org/jira/browse/SOLR-9789
> Project: Solr
> Issue Type: Bug
> Components: SolrCloud
> Affects Versions: 5.5.1
> Reporter: Gary Lee
> Priority: Minor
>
> We ran into a situation where using ZkCLI to get the Solr clusterstate in
> Zookeeper always returned a NPE. We eventually found that it was due to a
> clusterstate being too large (over 1M Zookeeper node limit) so the
> zkClient.getData call returned null, but it was confusing to instead throw an
> NPE because ZkCLI assumes non-null byte data. Could a check be added to not
> throw NPE, but report a warning instead?
