Matteo Bertozzi commented on HBASE-13331:
-----------------------------------------
[~eclark] sorry I'm late here, why didn't you change the IOException in
something like RegionDirNotFound or similar? instead of having the exists check
also outside?
{code}
public static HRegionFileSystem openRegionFromFileSystem(final Configuration
conf,
final FileSystem fs, final Path tableDir, final HRegionInfo regionInfo,
boolean readOnly)
...
if (!fs.exists(regionDir)) {
LOG.warn("Trying to open a region that do not exists on disk: " +
regionDir);
throw new IOException("The specified region do not exists on disk: " +
regionDir);
}
{code}
> Exceptions from DFS client can cause CatalogJanitor to delete referenced files

> CatalogJanitor#checkDaughterInFs assumes that there are no references
> whenever HRegionFileSystem.openRegionFromFileSystem throws IOException. Well
> Hadoop and HBase throw IOExceptions whenever someone looks in their general
> direction.
