---------------------------------------
By-pass this issue with HBASE-21588
> Encode ZNode names to reduce ZooKeeper jute buffer length requirements and
> thus reduce memory usage
> ---------------------------------------------------------------------------------------------------
>
> Key: HBASE-18396
> URL: https://issues.apache.org/jira/browse/HBASE-18396
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 3.0.0-alpha-1
> Reporter: Karan Mehta
> Priority: Major
>
> In our production environment, we hit the error {{ZooKeeper connectionLoss
> due to jute.maxbuffer len of 1M getting exceeded}}. Usually 1 MB is a lot,
> but in case of multi requests, it can exceed the maximum buffer length that
> is allocated.
> This JIRA is a discussion for encoding various znode names. IMO, this will
> reduce the path lengths, thus reducing the size of buffer required as well as
> network packet size and also pack more requests in a single multi. As with
> encoding, this will introduce overhead, but we need to determine how feasible
> this idea is.
