Lars Hofhansl commented on HBASE-3960:
--------------------------------------
Both of these would be M/R jobs. Should we generally allow the shell to trigger
M/R jobs?
> Add dump/load to the HBase shell

> URL: https://issues.apache.org/jira/browse/HBASE-3960
> Project: HBase
> Issue Type: New Feature
> Components: shell
> Reporter: Joey Echeverria
> Priority: Minor

> From the mailing list:
> That would be a real nice feature though, imagine going to the shell,
> and requesting a dump of your table.
> > load into outfile/hdfs '/tmp/table_a' from table_a
> Or something similar.
> > load from outfile/hdfs -- could power bulk uploader
> Further discussion suggested that for large tables, the commands should
> launch a MR job (assuming a JobTracker is available).
