Subject [jira] Commented: (HBASE-484) Store HRegionInfo in META and ROOT as multiple cells instead of a binary field
Date Wed, 16 Jul 2008 22:51:31 GMT

    [ https://issues.apache.org/jira/browse/HBASE-484?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12614142#action_12614142

Jean-Daniel Cryans commented on HBASE-484:

I don't think it will be needed anymore. +1 on closing this jira.

>                 Key: HBASE-484
>                 URL: https://issues.apache.org/jira/browse/HBASE-484
>             Project: Hadoop HBase
>          Issue Type: Improvement
>          Components: master, regionserver
>            Reporter: Bryan Duxbury
>            Priority: Trivial
> Right now we keep our HRegionInfos stored as a stream of bytes in a single column in
the META and ROOT tables. This is convenient to build and write in code under normal circumstances,
and we've made the shell deserialize the binary into human readable data for display purposes.
> However, we really don't have much flexibility to edit the info through the shell since
it's binary. This means that when we need some latitude to reach in and tweak some stuff because
of bugs or just for experimental purposes, we have to go and write custom tools in Java to
achieve anything.
> One way to mitigate this problem would be to stop storing HRIs as binary data and start
putting each field into separate first-class columns in META and ROOT. This would let us do
whatever we want in terms of single-row operations in the shell. We wouldn't have to make
a special case for reading the data in those circumstances then, either.
