我有 5 个节点 Hortonworks 集群（版本 - 2.4.2），我在其中安装了 Hawq 2.0.0。
这5个节点是：edge master（Name节点）node1（Data Node1）node2（Data Node2）node3（Data Node3）
我按照这个链接在 HDP 中安装 Hawq - http://hdb.docs.pivotal.io/hdb/install/install-ambari.html
Hawq 组件安装在这些节点中：
Hawq 主节点 - 节点 1 Hawq 备用主节点 - 节点 2
hawq 段 - node1,node2,node3
在安装时，Hawq master、Hawq standy master、hawq 段已成功安装，但在 Ambari 中由 Hawq 安装程序运行的基本 Hawq 测试失败：
下面在Installer执行的操作中

--- 上面我们可以看到，drop 和 Create table 被执行了，但是 insert 操作没有成功。
所以，我在 Hawq 主节点上手动执行了插入命令，即 node1
这些是手动执行的步骤：
[root@node1 ~]# su - gpadmin
[gpadmin@node1 ~]$ psql
psql (8.4.20, server 8.2.15)
WARNING: psql version 8.4, server version 8.2.
Some psql features might not work.
Type "help" for help.
gpadmin=#
gpadmin=# \c gpadmin
psql (8.4.20, server 8.2.15)
WARNING: psql version 8.4, server version 8.2.
Some psql features might not work.
You are now connected to database "gpadmin".
gpadmin=# create table test(name varchar);
gpadmin=# insert into test values('vikash');
-- 上面的插入操作时间长了就报错了
错误：无法从资源管理器获取资源，由于没有可用的集群，资源请求超时（pquery.c:804）
此外，节点 1 中的 hawq 段日志将作为

我也曾尝试检查“gp_segment_configuration”
gpadmin=# select * from gp_segment_configuration
gpadmin-# ;
registration_order | role | status | port | hostname | address | description

0 | m | u | 5432 | node1 | node1 |
1 | p | d | 40000 | node1.localdomain | 2.10.1.71 | resource manager process was reset
(3 rows)
注意：在 hawq-site.xml 中，资源管理类型从下拉列表中选择为“ STANDALONE ”而不是“YARN”。
任何人都有任何线索，这里有什么问题？？？提前致谢 ！！！
