CatalogJanitor doesn't work properly when "fs.default.name" isn't set in config
file.
-------------------------------------------------------------------------------------
Key: HBASE-4184
URL: https://issues.apache.org/jira/browse/HBASE-4184
Project: HBase
Issue Type: Bug
Components: master
Reporter: Ming Ma
Assignee: Ming Ma
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:///
