[jira] [Resolved] (HBASE-5842) Passing shell commands as an argument

["Harsh J (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-5842?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Harsh J resolved HBASE-5842.
----------------------------

    Resolution: Later

[~busbey] - It partially improves the first form, but I still feel a {{-c}} option may be preferable, no?

That said I've not seen need for scanning meta lately (HBase has improved a lot!) so I'll resolve this one as 'Later' as there's no demand on this.

I cannot also think of many other reasons one would need to be piping to the current shell instead of using the file option (if at all).

> 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 like:
> {{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.]
