Date Thu, 26 Apr 2012 02:47:17 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5842?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13262334#comment-13262334

Jonathan Hsieh commented on HBASE-5842:

A greppable dump would be really helpful for system tests and for surgery. :)  What versions
of hbase did this exist in?

>                 Key: HBASE-5842
>                 URL: https://issues.apache.org/jira/browse/HBASE-5842
>             Project: HBase
>          Issue Type: Improvement
>          Components: shell
>    Affects Versions: 0.94.0
>            Reporter: Harsh J
>            Priority: Minor
> Many times we've required scans of .META. to analyze issues with the cluster we work
on, and to have the result in a file we can pass around we usually end up doing something
> {{echo "scan '.META.'| hbase shell > meta-scan.txt}}
> This can rather be simplified as something like the following instead, with support for
a commands reading argument:
> {{hbase shell -c "scan '.META.'"}}
> [Note though: File reading is possible already, i.e. {{hbase shell file.hs}}, but then
thats two steps and we usually don't keep a file around for just a meta table scan.]
