Subject [jira] [Commented] (HBASE-8304) Bulkload fail to remove files if fs.default.name / fs.defaultFS is configured without default port.
Date Fri, 07 Mar 2014 01:03:16 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13923341#comment-13923341

Andrew Purtell commented on HBASE-8304:
---------------------------------------

Minor nit, use different IP addresses in the test here, not just different ports. It will
be more clear that way.

{code}
+    conf.set("dfs.namenode.rpc-address.haosong-hadoop.nn1", "127.0.0.1:8020");
+    conf.set("dfs.namenode.rpc-address.haosong-hadoop.nn2", "127.0.1.1:8000");
+    desPath = new Path("/");
+    desFs = desPath.getFileSystem(conf);
+    assertTrue(FSHDFSUtils.isSameHdfs(conf, srcFs, desFs));
+

> When fs.default.name or fs.defaultFS in hadoop core-site.xml is configured as hdfs://ip,
and hbase.rootdir is configured as hdfs://ip:port/hbaserootdir where port is the hdfs namenode's
default port. the bulkload operation will not remove the file in bulk output dir. Store::bulkLoadHfile
will think hdfs:://ip and hdfs:://ip:port as different filesystem and go with copy approaching
instead of rename.
> The root cause is that hbase master will rewrite fs.default.name/fs.defaultFS according
to hbase.rootdir when regionserver started, thus, dest fs uri from the hregion will not matching
src fs uri passed from client.
> any suggestion what is the best approaching to fix this issue? 
> I kind of think that we could check for default port if src uri come without port info.
