> Key: HBASE-20282
> URL: https://issues.apache.org/jira/browse/HBASE-20282
> Project: HBase
> Issue Type: Bug
> Components: documentation, tooling
> Reporter: Mike Drob
> Priority: Major
> Labels: beginner
>
> We have some tooling that can be made more friendly.
> {{bin/hbase ltt}} with no arguments should print usage instead of a stack
> trace.
> {{bin/hbase canary}} usage should refer to itself as {{canary}} not
> {{o.a.h.h.tool.Canary}}
> {{bin/hbase org.apache.hadoop.hbase.util.RegionSplitter}} should be shortened
> to {{bin/hbase regionsplitter}}. Usage should be updated to reflect the short
> name.
> The fix here MUST also include updates to the book/documentation for the
> tools.
