我在Ubuntu 16.04上运行jena-fuseki服务器。我试图加载数据集如下：
./fuseki-server --loc="/home/dataset.json.bz2" /ds
保持弹出的错误如下：

尝试加载的数据集I的大小约为120 GB。我也尝试通过提取数据集并加载json格式来加载。此外，我试图加载数据集的.nt（N三元组）格式。但是同样的错误发生了。 localhost：3030说 HTTP错误503访问/的问题。原因：服务不可用

--loc=为TDB1数据库命名目录。目录必须存在;它可以是空的，也可以包含预建的数据库。
dataset.json.bz2看起来像一个文件。
如果它包含RDF数据，则首先使用tdbloader构建数据库。
