Nutanix VM中的Cloudera

m
徽章 +1
大家好！有人在Nutanix环境中运行Cloudera吗？不仅是Hadoop，而且是企业Cloudera Hadoop实施。我们正在将生产Cloudera群集迁移到Nutanix VM，并存在与磁盘延迟有关的许多问题。我知道Nutanix Hadoop参考文档，但是我们的配置并不完全合适，因为它始于物理设备，并且现有的生产配置在这一点上更改将具有挑战性。例如，我们还没有运行纱线，但仍在MapReduce V1上，尽管我们正在开发环境中移动该方向。



我们有一个专门用于HDFS目录的存储容器，在VMware中用它雕刻出虚拟磁盘，但是我们看到Vdisk Letch lestencies *平均 * 300ms，经常出现几秒钟。我们的I/O写得很重；Nutanix建议我们禁用EC-X，所以我们做到了，但没有帮助。我们正在该容器上运行RF2，没有重复数据删除，内联压缩。VDisk被分区，分区上有Ext4文件系统，安装在“ Noatime”上。



如果有人成功地在nutanix上开辟了一个克卢德拉环境，那么您发现了什么（解决）？我很有可能愚蠢地配置了一些东西，但是我无法弄清楚它可能是什么。谢谢！

    \nWe have a storage container devoted to our HDFS directories, with virtual disks carved out of it in VMWare, but we're seeing vdisk latencies *averaging* 300ms with frequent spikes to several seconds. Our I\/O is very write heavy; Nutanix advised us to disable EC-X, so we did, but no help. We're running RF2 on that container, no deduplication, inline compression. vdisks are partitioned, with ext4 filesystems on the partitions, mounted \"noatime.\"

    \n

    \nIf anyone's successfully spun-up a Cloudera environment on Nutanix, what gotchas have you found (and solved)? It's entirely possible I've configured something foolishly, but I can't for the life of me figure out what it might be.

    您要连接几个VDS？不是Cloudera，但我只是通过SAS-GRID POC进行了工作，我们看到了4到8的进步。

    每个VM上都有4个2TB VDISK。我不确定我可以去8，容器中没有足够的空间；我可能必须删除一些并将其添加回去。您是否有任何猜测，为什么这种变化解决了您的问题？谢谢！！！
