Description

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.]
