Zhe Zhang updated HDFS-10544: ----------------------------- Attachment: HDFS-10544.00.patch Submitting initial patch. {{HAUtil#useLogicalUri}} can potentially be optimized to avoid creating an instance of {{AbstractNNFailoverProxyProvider}}. > Balancer doesn't work with IPFailoverProxyProvider > -------------------------------------------------- > > Key: HDFS-10544 > URL: https://issues.apache.org/jira/browse/HDFS-10544 > Project: Hadoop HDFS > Issue Type: Bug > Reporter: Zhe Zhang > Assignee: Zhe Zhang > Attachments: HDFS-10544.00.patch > > > Right now {{Balancer}} gets the NN URIs through > {{DFSUtil#getNameServiceUris}}, which returns logical URIs in HA is enabled. > If {{IPFailoverProxyProvider}} is used, {{Balancer}} will not be able to > start. > I think the bug is at {{DFSUtil#getNameServiceUris}}: > {code} > for (String nsId : getNameServiceIds(conf)) { > if (HAUtil.isHAEnabled(conf, nsId)) { > // Add the logical URI of the nameservice. > try { > ret.add(new URI(HdfsConstants.HDFS_URI_SCHEME + "://" + nsId)); > {code} > Then {{if}} clause should also consider if the {{FailoverProxyProvider}} has > {{useLogicalURI}} enabled. If not, {{getNameServiceUris}} should try to > resolve the physical URI for this nsId. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
