[jira] [Created] (HBASE-7175) [snapshots] SnapshotFileVisitor
should allow short-circuit for skipping directories
Jesse Yates created HBASE-7175:
----------------------------------
Summary: [snapshots] SnapshotFileVisitor should allow short-circuit for skipping directories
Key: HBASE-7175
URL: https://issues.apache.org/jira/browse/HBASE-7175
Project: HBase
Issue Type: Improvement
Affects Versions: hbase-6055
Reporter: Jesse Yates
Often times when we use the FileVisitor, we don't need to collect all the files in the snapshot, but really just a subset. In the current implementation, we still look at all the files in all the subfolders in the the snapshot, which puts extra stress on an already stressed namenode.
A simple implementation can just use a simple PathFilter to determine which files/directories should be passed to the FileVisitor.
