Andrew Purtell resolved HBASE-11584.
------------------------------------
Resolution: Invalid
Please mail [email protected] for reporting potential problems and
community assistance in troubleshooting. JIRA isn't the correct forum for
reporting problems until the cause is known. Nothing reported on this issue
indicates encryption is more than an incidental detail. We don't encrypt the
META table. There could be many reasons why you lost your HFiles. Did you keep
the test configuration that puts the HBase root in /tmp for example. Anyway,
please don't reply here, take this to [email protected].
> HBase file encryption, consistences observed and data loss
> ----------------------------------------------------------
>
> Key: HBASE-11584
> URL: https://issues.apache.org/jira/browse/HBASE-11584
> Project: HBase
> Issue Type: Bug
> Components: hbck, HFile
> Affects Versions: 0.98.3
> Environment: SuSE 11 SP3
> Reporter: shankarlingayya
> Priority: Critical
>
> HBase file encryption some consistences observed and data loss happens after
> running the hbck tool,
> the operation steps are as below.
> Procedure:
> 1. Start the Hbase services (HMaster & region Server)
> 2. Enable HFile encryption and WAL file encryption as below, and perform
> 'table4-0' put operations (100 records added)
