> Problem with row keys beginnig with characters < than ',' and the region

> Key: HBASE-832
> URL: https://issues.apache.org/jira/browse/HBASE-832
> Project: Hadoop HBase
> Issue Type: Bug
> Components: client, regionserver
> Affects Versions: 0.2.0
> Reporter: Jean-Daniel Cryans
> Priority: Blocker
> Fix For: 0.2.1, 0.18.0
>
>
> We currently have a problem the way we design .META. row keys. When user
> table row keys begin with characters lesser than ',' like a '$', any
> operation will fail when:
> - A client has a certain set of regions in cache
> - One region with the faulty row key splits
> - The client receives a request for a row in the split region
> The reason is that it will first get a NSRE then it will try to locate a
> region using the passed row key. For example:
> Row in META: entities,,1216750777411
> Row passed: entities,$-94f9386f-e235-4cbd-aacc-37210a870991,99999999999999
> The passed row is lesser then the row in .META.
