> As HBASE-16466 commented.
> Seems like that when source hbase cluster / peer hbase cluster / yarn cluster
> locate in three different HDFS cluster , it has one problem.
> when restoring the snapshot into tmpdir , we need to create region by
> following code (HRegion#createHRegion)
> {code}
> public static HRegion createHRegion(final HRegionInfo info, final Path
> rootDir,
> final Configuration conf, final TableDescriptor hTableDescriptor,
> final WAL wal, final boolean initialize)
> throws IOException {
> LOG.info("creating HRegion " + info.getTable().getNameAsString()
> + " HTD == " + hTableDescriptor + " RootDir = " + rootDir +
> " Table name == " + info.getTable().getNameAsString());
> FileSystem fs = FileSystem.get(conf);
> <------------------- Here our code use fs.defaultFs configuration to create
> region.
> Path tableDir = FSUtils.getTableDir(rootDir, info.getTable());
> HRegionFileSystem.createRegionOnFileSystem(conf, fs, tableDir, info);
> HRegion region = HRegion.newHRegion(tableDir, wal, fs, conf, info,
> hTableDescriptor, null);
> if (initialize) region.initialize(null);
> return region;
> }
> {code}
> When source cluster & peer cluster locate in two difference file systems ,
> then their fs.defaultFs should be difference, so at least one cluster will
> fail when restore snapshot into tmpdir . after I added the following fix, it
> works fine for me.
> {code}
> -FileSystem fs = FileSystem.get(conf);
> +FileSystem fs = rootDir.getFileSystem(conf);
> {code}
