> Project: HBase
> Issue Type: Bug
> Components: mapreduce, snapshots

> Reporter: deepankar
> Fix For: 0.99.0, 0.96.3, 0.98.4

> In class *TableSnapshotInputFormat* or *TableSnapshotInputFormatImpl*
> in the function
> {code}
> public static void setInput(Job job, String snapshotName, Path restoreDir)
> throws IOException {
> {code}
> we are setting restoreDir (temporary root) to tableDir
> {code}
> conf.set(TABLE_DIR_KEY, restoreDir.toString());
> {code}
> The above parameter is used to get the InputSplits, especially for
> calculating favorable hosts in the function
> {code}
> Path tableDir = new Path(conf.get(TABLE_DIR_KEY));
> List<String> hosts = getBestLocations(conf,
> HRegion.computeHDFSBlocksDistribution(conf, htd, hri, tableDir));
> {code}
> This will lead to returning a empty *HDFSBlocksDistribution*, as there is
> will be no directory with name as the region name from hri in the restored
> root directory, which will lead to scheduling of non local tasks.
> The change is simple in the sense, is to call the
> {code}FSUtils.getTableDir(rootDir, tableDesc.getTableName()) {code}
> in the getSplits function
