Already tried 0 time(s); retry policy is RetryUpToMaximumCountWithFixedSleep(maxRetries=10, sleepTime=1 SECONDS) 這個問題是由於沒有啟動historyserver引起的,解決辦法: 在mapred-site.xml配置文件中添加: <property> <name>mapreduce.jobhistory.address</name> <value>sjfx:10020</value> </property> 在namenode上執行命令:mr-jobhistory-daemon.sh start historyserver 這樣在,namenode上會啟動JobHistoryServer服務,可以在historyserver的日誌中查看運行情況 2、14/04/04 17:20:00 INFO mapreduce.Job: Task Id : attempt_1396530865591_0003_m_000011_0, Status : FAILED 出現這個問題可能是由於集群性能瓶頸造成的(IO或網絡問題等等) 之前在臺式機上虛擬出三個slave的集群,數據量稍微大點就會出現這個問題,後來換了臺服務器虛擬出兩個slave的集群,沒有出現這個問題。 3、mapreduce歷史作業管理器相關知識(出自:董成西《Hadoop技術內幕 深入解析yarn架構設計與實現原理》): 為了方便用戶查看MapReduce歷史作業信息,MRAppMaster提供了一個JobHistoryServer服務,該服務主要由四個子服務組成,具體如下: a、HistoryClientService.為Web界面展示歷史作業信息提供後端實現,它通過調用JobHistory中的相關API獲取作業信息,比如提交時間、提交用戶、Counter值等,並將這些信息發送到前端。 b、HSAdminServer。管理員可使用“bin/mapred hsadmin” 命令動態更新JobHistoryServer訪問和管理權限信息。用戶輸入該命令後,後端的HSAdminService服務將執行該命令,當前該命令可動態更新以下幾種信息: ①管理員列表。歷史作業查看器的管理員列表(具有啟動和停止JobHistoryServer服務、更新權限信息等權限)是通過core-site.xml中的mapreduce.jobhistory.admin.acl屬性(默認是“*”,表示任何人都是管理員)設置的。 ②超級用戶組列表。超級用戶組信息是通過core-site.xml中的hadoop.proxyuser.groups和hadoop.proxyuser.hosts屬性設置的,超級用戶組是hadoop引入Kerberos安全機制後,為方便上層應用(比如HBase、Oozie等)訪問Hadoop內核服務而新增加的配置項。 ④用戶與用戶組映射關系。用戶與用戶組映射關系是通過core-site.xml中的hadoop.security.group.mapping屬性設置的,它需要是一個實現了GroupMappingServiceProvider接口的類,默認實現是ShellBasedUnixGroupsMapping,即采用Linux操作系統的用戶和用戶組映射關系。 c、AggregatedLogDeletionService。該服務周期性掃描所有歷史作業日誌目錄,如果一個日誌目錄存放時間超過yarn.nodemanager.log.retain-seconds(單位是秒,默認為3*60*60,即三個小時),則直接將其從HDFS上刪除。 d、JobHistory。該服務從HDFS上讀取MapReduce歷史作業日誌,並將其解析成格式化信息,供前端查看。MRAppMaster將執行完成的作業信息保存到mapreduce.jobhistory.intermediate-done-dir指定的目錄中,如果用戶未設置該屬性,則保存到${yarn.app.mapreduce.am.staging-dir}/history/done_intermediate目錄中,其中每個作業保存作業配置文件(後綴為.xml)和作業執行日誌(後綴為.jhist)兩個文件,通過解析作業執行日誌,JobHistory能獲取作業執行時的所有信息,包括作業提交時間、作業Counter、每個任務提交時間和運行時間、每個任務的Counter等。
