hbase shell deleteall to .META. allows insertion of malformed rowkey.
---------------------------------------------------------------------
Key: HBASE-5837
URL: https://issues.apache.org/jira/browse/HBASE-5837
Project: HBase
Issue Type: Bug
Components: master, shell
Affects Versions: 0.90.6
Reporter: Jonathan Hsieh
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.
