Question

我正在尝试将tsv文件加载到现有的hbase表中。我使用以下命令：

/usr/local/hbase/bin$ hbase org.apache.hadoop.hbase.mapreduce.ImportTsv -Dimporttsv.columns=HBASE_ROW_KEY,cf:value '-Dtable_name.separator=\t' Table-name /hdfs-path-to-input-file

但是当我执行上面的命令时，我收到以下错误

Container id: container_1434304449478_0018_02_000001
Exit code: 1
Stack trace: ExitCodeException exitCode=1:

Failing this attempt. Failing the application.

在通过UI进一步挖掘Container日志时，我收到以下错误

2015-06-16 13:28:02,776 ERROR [main] org.apache.hadoop.mapreduce.v2.app.client.MRClientService: Webapps failed to start. Ignoring for now:

我在多节点群集上使用Hadoop-2.6.0和Hbase-0.98版本。

我无法理解造成此错误的原因。请指导我。

Answer 1

java.lang.ClassNotFoundException: Class org.apache.hadoop.yarn.server.webproxy.amfilter.AmFilterInitializer not found

上述行清楚地表明您缺少Web代理jar。

您需要在Hbase lib文件夹中添加以下jar。

hadoop-yarn-server-web-proxy-2.6.0.jar

Importtsv命令给出：容器退出时出现非零退出代码1错误
