我正在尝试将tsv文件加载到现有的hbase表中。我正在使用以下命令：

/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，我得到以下错误

Container id: container_1434304449478_0018_02_000001
Exit code: 1

在通过ui进一步挖掘容器日志时，我得到以下错误

我在多节点集群上使用hadoop-2.6.0和hbase-0.98版本。
我不明白是什么导致了这个错误。请引导我。
