> Project: HBase
> Issue Type: Bug
> Components: master, shell
> Affects Versions: 0.90.6, 0.96.0

> When using the hbase shell to manipulate meta entries, one is allowed to
> 'delete' malformed rows (entries with less than 2 ascii 44 ',' chars). When
> this happens HBase servers may go down and the cluster will not be
> restartable without manual intervention.
> The delete results in a durable malformed rowkey in .META.'s memstore,
> .META.'s HLog, and eventually .META.'s HFiles. Subsequent scans to meta
> (such as when a HMaster starts) fail in the scanner because the comparator
> fails. In the case of an HMaster startup, it causes an abort that kills the
> HMaster process.
