Ted Yu commented on HBASE-4184:
-------------------------------
+1 on patch.
Andrew argued that HRegionInfo.getTableDesc() should be kept for one major
release before being removed.
> CatalogJanitor doesn't work properly when "fs.default.name" isn't set in
> config file.

> In our system, hbase.rootdir is set to a hdfs path and hbase can figure out
> the FileSystem and set "fs.default.name" accordingly on the Configuration
> object and pass around including to RS. That is handled in HMaster.java and
> MasterFileSystem.java.
> CatalogJanitor uses deprecated HRegionInfo.getTableDesc. The method creates a
> default configuration and get FileSystem from there. That will be
> RawLocalFileSystem. It returns the following exception.
> java.lang.IllegalArgumentException: Wrong FS:
> hdfs://sea-esxi-0:54310/tmp/hbase/
> testtb/.tableinfo, expected: file:///
