Subject SnapshotInputFormat long initialization time.
Date Tue, 08 Apr 2014 14:19:54 GMT
Hi all,

I backported SnapshotInputFormat to hbase 0.94. This resulted in a huge
performance gain while the scan is running. Here is the corresponding jira
https://issues.apache.org/jira/browse/HBASE-8369. The overall performance
gain is mitigated by a very long initialization period. It can take up to
30 minutes after the snapshot completes for the MR job to actually begin.

Does anybody have experience running SnapshotInputFormay on 0.94 or 0.98?
Are you seeing the same long initialization period?
