Jonathan Hsieh created HBASE-6812:
-------------------------------------
Summary: Export dry run mode.
Key: HBASE-6812
URL: https://issues.apache.org/jira/browse/HBASE-6812
Project: HBase
Issue Type: Bug
Components: mapred
Reporter: Jonathan Hsieh
We encountered customer experiencing poor performance on Exports and we've
spent some time trying to isolate the performance bottlenecks. It was
suggested to add a "dry run mode" that just scans the table but does not emit
data to hdfs. This would be really useful for determining if problems are on
the write path or the read path.
