Subject [jira] Resolved: (HBASE-1149) Dataloss when master and region server die at same time
Date Tue, 07 Dec 2010 20:51:09 GMT

     [ https://issues.apache.org/jira/browse/HBASE-1149?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

stack resolved HBASE-1149.

    Resolution: Invalid

 In 0.90 we have working flush and new master makes it so more tolerant of fail of master
and regionserver (There are unit tests that have master and a regionserver die and then we
run recover).  Lets open specific issues for problems in the new stuff.  Resolving as stale/invalid.

>             Project: HBase
>          Issue Type: Bug
>    Affects Versions: 0.19.0
>            Reporter: Ben Maurer
> To reproduce:
> 1) Run HBase in standalone mode
> 2)
> create 'foo', 'bar'
> 3) kill -9 the HBase server
> 4) Restart hbase
> The table 'foo' will not exist.
> Apparently this problem happens because the master and region servers die at the same
time. To me that suggests a fairly large flaw -- if your cluster has a systematic failure
(say, a power outage) it would cause data loss.
