我在red hat linux enterprise 6上有一个具有1个namenode和4个DataNode的集群。我的hdp版本是2.1。ambari的版本是1.7，但我把它升级到了2.1。我想把hdp升级到2.2版本。我读到如果我想把hdp从2.1升级到2.2，我必须在ambari升级到2.1之前完成。当我升级hdp到2.2ambari没有看到任何变化，一切都不工作。我正在使用此教程：http://docs.hortonworks.com/hdpdocuments/hdp2/hdp-2.2.0/hdp_man_upgrade_v22/index.html#item1
我该怎么做？我试着把ambari降到1.7，但是我犯了很多错误。如果我现在尝试将hdp升级到2.2，然后将ambari从2.1升级到2.1.1呢。行吗？问题是我的时间很少。先谢谢你

我正在开发/测试集群上从hdp-2.0/hadoop-2.2升级到hdp-2.2/hadoop-2.6（可能是暂时的，在升级到hdp-2.3的途中）。到目前为止，我已经得到了更新的hdfs和运行。尚未通过ambari启动/停止hdfs，也未运行Yarn。更新：在找到hdp-2.2文档（下面添加了当前链接）之后，我得到了yarn、mapreduce和hive来运行。
以下是我关于如何走到这一步的粗略记录：
升级ambari-1.4至1.7
在每个节点上更新hdp-yum-repo文件并用yum（cssh）更新http://public-repo-1.hortonworks.com/hdp/centos6/2.x/updates/2.2.6.0/hdp.repo
hdp选择
sudo su-l hdfs-c“/usr/hdp/current/hadoop client/sbin/hadoop-daemon.sh start namenode-升级”
/etc/hadoop/conf.empty/core-site.xml.rpmsave、hdfs-site.xml
sudo su-l hdfs-c“/usr/hdp/current/hadoop hdfs datanode/。/hadoop/sbin/hadoop-daemon.sh start datanode”
hadoop dfsadmin-终结升级
[更新]
升级ambari-1.7至2.1
配置yarn&mapreduce-yarn-site.xml、yarn env.sh[？]、container-executor.cfg、mapred-site.xml
sudo ln-s/usr/hdp/2.2.6.0-2800/hadoop/libexec//usr/lib/hadoop/#ambari/usr/lib/hadoop
停止启动resourcemanager，启动NodeManager
conf.dist和conf.server中的hive-site.xml；手动启动
