Subject [jira] [Commented] (HBASE-8304) Bulkload fail to remove files if fs.default.name / fs.defaultFS is configured without default port.
Date Mon, 24 Feb 2014 07:42:20 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8304?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13910080#comment-13910080

haosdent commented on HBASE-8304:
---------------------------------

[~brandonli] I found getCanonicalServiceName() may be a better way. But I think we still handle
some special case in HA. For example: srcFs: hdfs://activeNN:port dstFs: hdfs://nameservices.
{code:java}
-    if (!srcFs.getUri().equals(desFs.getUri())) {
+    if (!srcFs.getCanonicalServiceName().equals(desFs.getCanonicalServiceName())) {
       LOG.info("Bulk-load file " + srcPath + " is on different filesystem than " +
           "the destination store. Copying file over to destination filesystem.");
       Path tmpPath = createTempName();
{code}

> 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.
