Matteo Bertozzi commented on HBASE-15806:
-----------------------------------------
the HRegion.getScanner() does not call the preScannerOpen() coprocessor.
looks like that call is only done by RSRpcServices when we receive the scan
request.
so, by skipping the coprocessor it means we can pass a scan on a table where we
don't have access and be able to get the dump of the data
> An endpoint-based export tool

> The time for exporting table can be reduced, if we use the endpoint technique
> to export the hdfs files by the region server rather than by hbase client.
> In my experiments, the elapsed time of endpoint-based export can be less than
> half of current export tool (enable the hdfs compression)
> But the shortcomings is we need to alter table for deploying the endpoint
> any comments about this? thanks
