PredictionIO pio状态:Zookeeper存在失败

我通过$ bash -c"$(curl -s https://install.prediction.io/install.sh)安装PredictionIO "

当我做pio状态时,它显示以下消息:

正如https://docs.prediction.io/resources/faq/中所建议的那样,我尝试通过$〜/ PredictionIO/vendors/hbase-xyz/bin/start-hbase.sh启动HBase ,但仍然存在相同的错误.

我可以尝试哪些其他解决方案？我需要手动安装zookeeper吗？(我认为快速安装已经安装了它).谢谢!

听起来HBase还没有正确初始化.首先尝试做pio-stop-all,然后pio-start-all再尝试pio status.如果这不起作用,则继续并pio-stop-all再次运行,然后通过键入以下命令查找正在运行的HBase实例ps aux | grep hbase,并关闭正在运行(使用kill -9 )的HBase的相应实例.pio-start-all再次输入后,您应该能够在pio status没有前面提到的错误的情况下运行.

由于您刚安装了PredictionIO,因此运行pio-start-all就足够了.但是,根据我的经验,如果您使用HBase,您可能会遇到必须手动终止该过程的情况,如上所述.
