I was looking at Export code. http://hbase.apache.org/apidocs/org/apache/hadoop/hbase/mapreduce/Export.html. I don't see "setCaching" called in the code. Wouldn't that would have speed up the hbase export. Is this intentional? or is it expected that user change this conf in hbase-site.xml according to their memory constraints. Am I missing anything here? 2. While running hbase export for backing up data, I am getting scanner timeout exceptions too. I can increase the regionserver.lease.period but not sure whether it's a good idea. Would be nice to hear some opinions. Any help greatly appreciated. Thanks, Jahangir. --f46d0408da2d07437b04b64cfa52--
