--------------------------------------

I plan to work on contributing a patch for this issue next week (mid September).

> Distributed mode does not compress state.json
> ---------------------------------------------
>
>                 Key: SOLR-17894
>                 URL: https://issues.apache.org/jira/browse/SOLR-17894
>             Project: Solr
>          Issue Type: Bug
>          Components: SolrCloud
>    Affects Versions: 9.0, 10.0
>            Reporter: Paul McArthur
>            Priority: Major
>              Labels: Compression, clusterstate
>
> When running SolrCloud with the Overseer enabled, ZKStateWriter compresses 
> state.json when it is written to ZooKeeper.
> This same compression does not happen when running in Solr Cloud's 
> distributed mode, without an Overseer (DistributedClusterStateUpdater).
>  
> In some cases, with very large collections, a cluster that runs with an 
> Overseer can encounter problems when transitioning to distributed mode where 
> updates to state.json persistently fail. This happens because the 
> uncompressed size of the data is too large to fit in the configured jute 
> buffer.
