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).
> Passing shell commands as an argument

> 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 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.]
