I am converting a secure non-HA cluster into a secure HA cluster. After the configuration and started all the journalnodes, I executed the following commands on the original NameNode: 1. hdfs name -initializeSharedEdits #this step succeeded 2. hadoop-daemon.sh start namenode # this step failed.
The namenode did not start successfully. I verified that my principals are right. And I checked the DNS is configured correctly so that I could use the nslookup command to lookup and reverse-lookup the Namenode and JournalNodes. I also checked the logs. The JournalNodes did not report any ERROR. The Namenode Log report some ERRORs, but I still could not find the reason according to these ERRORS. In the following I listed the main part of my hdfs-site.xml and the error log from my Namenode. Could anyone help me to figure it out? Many Thanks! **************The main part of my hdfs-site.xml************************* <property> <name>dfs.nameservices</name> <value>bgdt-dev-hrb</value> </property> <property> <name>dfs.ha.namenodes.bgdt-dev-hrb</name> <value>nn1,nn2</value> </property> <property> <name>dfs.namenode.rpc-address.bgdt-dev-hrb.nn1</name> <value>bgdt01.dev.hrb:9000</value> </property> <property> <name>dfs.namenode.rpc-address.bgdt-dev-hrb.nn2</name> <value>bgdt02.dev.hrb:9000</value> </property> <property> <name>dfs.namenode.shared.edits.dir</name> <value>qjournal://bgdt01.dev.hrb:8485;bgdt03.dev.hrb:8485;bgdt04.dev.hrb:8485/bgdt-dev-hrb</value> </property> <property> <name>dfs.client.failover.proxy.provider.bgdt-dev-hrb</name> <value>org.apache.hadoop.hdfs.server.namenode.ha.ConfiguredFailoverProxyProvider</value> </property> <property> <name>dfs.ha.fencing.methods</name> <value>sshfence shell(/bin/true) </value> </property> <property> <name>dfs.ha.fencing.ssh.private-key-files</name> <value>/home/hadoop/.ssh/id_rsa</value> </property> <property> <name>dfs.journalnode.edits.dir</name> <value>/bgdt/hadoop/hdfs/jn</value> </property> <property> <name>dfs.permissions.enabled</name> <value>true</value> </property> <property> <name>dfs.namenode.name.dir</name> <value>file:///bgdt/hadoop/hdfs/nn</value> <final>true</final> </property> <property> <name>dfs.datanode.name.dir</name> <value>file:///bgdt/hadoop/hdfs/dn</value> </property> <property> <name>dfs.namenode.http-address.bgdt-dev-hrb.nn1</name> <value>bgdt01.dev.hrb:50070</value> </property> <property> <name>dfs.namenode.http-address.bgdt-dev-hrb.nn2</name> <value>bgdt02.dev.hrb:50070</value> </property> <property> <name>dfs.permissions.superusergroup</name> <value>bgdtgrp</value> </property> <property> <name>dfs.block.access.token.enable</name> <value>true</value> </property> <property> <name>dfs.http.policy</name> <value>HTTP_ONLY</value> </property> <property> <name>dfs.namenode.https-address.bgdt-dev-hrb.nn1</name> <value>bgdt01.dev.hrb:50470</value> </property> <property> <name>dfs.namenode.https-address.bgdt-dev-hrb.nn2</name> <value>bgdt02.dev.hrb:50470</value> </property> <property> <name>dfs.namenode.keytab.file</name> <value>/etc/hadoop/keytab/hadoop.service.keytab</value> </property> <property> <name>dfs.namenode.kerberos.principal</name> <value>hdfs/_h...@bgdt.dev.hrb</value> </property> <property> <name>dfs.namenode.kerberos.https.principal</name> <value>host/_h...@bgdt.dev.hrb</value> </property> <property> <name>dfs.webhdfs.enabled</name> <value>true</value> </property> <property> <name>dfs.web.authentication.kerberos.principal</name> <value>http/_h...@bgdt.dev.hrb</value> </property> <property> <name>dfs.web.authentication.kerberos.keytab</name> <value>/etc/hadoop/keytab/hadoop.service.keytab</value> </property> <property> <name>dfs.journalnode.kerberos.principal</name> <value>hdfs/_h...@bgdt.dev.hrb</value> </property> <property> <name>dfs.journalnode.kerberos.https.principal</name> <value>host/_h...@bgdt.dev.hrb</value> </property> <property> <name>dfs.journalnode.kerberos.internal.spnego.principal</name> <value>http/_h...@bgdt.dev.hrb</value> </property> <property> <name>dfs.journalnode.keytab.file</name> <value>/etc/hadoop/keytab/hadoop.service.keytab</value> </property> *********************The Error Log from the Namenode****************************** 2015-02-03 17:42:06,020 INFO org.apache.hadoop.hdfs.server.namenode.FSImage: Start loading edits file http://bgdt04.dev.hrb:8480/getJournal?jid=bgdt-dev-hrb&segmentTxId=68994&storageInfo=-57%3A876630880%3A0%3ACID-ea4c77aa-882d-4adf-a347-42f1344421f3, http://bgdt01.dev.hrb:8480/getJournal?jid=bgdt-dev-hrb&segmentTxId=68994&storageInfo=-57%3A876630880%3A0%3ACID-ea4c77aa-882d-4adf-a347-42f1344421f3 2015-02-03 17:42:06,024 INFO org.apache.hadoop.hdfs.server.namenode.EditLogInputStream: Fast-forwarding stream 'http://bgdt04.dev.hrb:8480/getJournal?jid=bgdt-dev-hrb&segmentTxId=68994&storageInfo=-57%3A876630880%3A0%3ACID-ea4c77aa-882d-4adf-a347-42f1344421f3, http://bgdt01.dev.hrb:8480/getJournal?jid=bgdt-dev-hrb&segmentTxId=68994&storageInfo=-57%3A876630880%3A0%3ACID-ea4c77aa-882d-4adf-a347-42f1344421f3' to transaction ID 68994 2015-02-03 17:42:06,024 INFO org.apache.hadoop.hdfs.server.namenode.EditLogInputStream: Fast-forwarding stream 'http://bgdt04.dev.hrb:8480/getJournal?jid=bgdt-dev-hrb&segmentTxId=68994&storageInfo=-57%3A876630880%3A0%3ACID-ea4c77aa-882d-4adf-a347-42f1344421f3' to transaction ID 68994 2015-02-03 17:42:06,154 ERROR org.apache.hadoop.hdfs.server.namenode.EditLogInputStream: caught exception initializing http://bgdt04.dev.hrb:8480/getJournal?jid=bgdt-dev-hrb&segmentTxId=68994&storageInfo=-57%3A876630880%3A0%3ACID-ea4c77aa-882d-4adf-a347-42f1344421f3 java.io.IOException: org.apache.hadoop.security.authentication.client.AuthenticationException: GSSException: No valid credentials provided (Mechanism level: Server not found in Kerberos database (7) -
