HDP的ambari集成安装工具真的是比ClouderaManager差上那么一点儿，不说安装的时候就麻烦，即使软件安装包已成功安装，也不意味着可以正常使用了，启动HDP集群过程中还会有不少的错误！
一、启动服务时，出现若干循环符号链接错误，比如下面是启动ranger时发生的其中一个错误信息：
setup_tagsync(upgrade_type=upgrade_type) File "/var/lib/ambari-agent/cache/stacks/HDP/3.0/services/RANGER/package/scripts/setup_ranger_xml.py", line 515, in setup_tagsync create_parents = True File "/usr/lib/ambari-agent/lib/resource_management/core/base.py", line 166, in __init__ self.env.run() File "/usr/lib/ambari-agent/lib/resource_management/core/environment.py", line 160, in run self.run_action(resource, action) File "/usr/lib/ambari-agent/lib/resource_management/core/environment.py", line 124, in run_action provider_action() File "/usr/lib/ambari-agent/lib/resource_management/core/providers/system.py", line 177, in action_create raise Fail("Applying %s failed, looped symbolic links found while resolving %s" % (self.resource, path)) resource_management.core.exceptions.Fail: Applying Directory[‘/usr/hdp/current/ranger-tagsync/conf‘] failed, looped symbolic links found while resolving /usr/hdp/current/ranger-tagsync/conf
解决办法，删掉错误的符号链接，建立正确的链接：
cd /usr/hdp/current/ranger-tagsync unlink conf ln -s /etc/ranger-tagsync/3.0.0.0-1634/0 conf
二、权限错误: Permission denied，详见下面log信息
stderr: /var/lib/ambari-agent/data/errors-919.txt Traceback (most recent call last): File "/var/lib/ambari-agent/cache/stacks/HDP/3.0/services/RANGER/package/scripts/ranger_admin.py", line 236, in <module> RangerAdmin().execute() File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 351, in execute method(env) File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 968, in restart self.stop(env, upgrade_type=upgrade_type) File "/var/lib/ambari-agent/cache/stacks/HDP/3.0/services/RANGER/package/scripts/ranger_admin.py", line 61, in stop Execute(format(‘{params.ranger_stop}‘), environment={‘JAVA_HOME‘: params.java_home}, user=params.unix_user) File "/usr/lib/ambari-agent/lib/resource_management/core/base.py", line 166, in __init__ self.env.run() File "/usr/lib/ambari-agent/lib/resource_management/core/environment.py", line 160, in run self.run_action(resource, action) File "/usr/lib/ambari-agent/lib/resource_management/core/environment.py", line 124, in run_action provider_action() File "/usr/lib/ambari-agent/lib/resource_management/core/providers/system.py", line 263, in action_run returns=self.resource.returns) File "/usr/lib/ambari-agent/lib/resource_management/core/shell.py", line 72, in inner result = function(command, **kwargs) File "/usr/lib/ambari-agent/lib/resource_management/core/shell.py", line 102, in checked_call tries=tries, try_sleep=try_sleep, timeout_kill_strategy=timeout_kill_strategy, returns=returns) File "/usr/lib/ambari-agent/lib/resource_management/core/shell.py", line 150, in _call_wrapper result = _call(command, **kwargs_copy) File "/usr/lib/ambari-agent/lib/resource_management/core/shell.py", line 314, in _call raise ExecutionFailed(err_msg, code, out, err) resource_management.core.exceptions.ExecutionFailed: Execution of ‘/usr/hdp/current/ranger-admin/ews/ranger-admin-services.sh stop‘ returned 126. -bash: /usr/hdp/current/ranger-admin/ews/ranger-admin-services.sh: Permission denied
解决办法，添加执行权限：
chmod a+x ranger-admin-services.sh
