I resolve the problem. The cause of the error is that when Solr is installed, Solr user and group can not be created automatically. I add Solar user and its group manually from the terminal with this command (1004 is the Oozie's group id):   useradd -g 1004 infra-solr -m -d /home/infra-solr --shell /bin/bash      ... View more

Hello,   I'm trying to install Infra Solr from Ambari. After installation, when i restart the Infra Solr, the status of the service is red and it gives error below:   Traceback (most recent call last): File "/usr/lib/ambari-agent/lib/resource_management/core/providers/system.py", line 51, in _ensure_metadata _user_entity = pwd.getpwnam(user) KeyError: 'getpwnam(): name not found: infra-solr' The above exception was the cause of the following exception: Traceback (most recent call last): File "/var/lib/ambari-agent/cache/common-services/AMBARI_INFRA_SOLR/0.1.0/package/scripts/infra_solr.py", line 171, in <module> InfraSolr().execute() File "/usr/lib/ambari-agent/lib/resource_management/libraries/script/script.py", line 351, in execute method(env) File "/var/lib/ambari-agent/cache/common-services/AMBARI_INFRA_SOLR/0.1.0/package/scripts/infra_solr.py", line 54, in start self.configure(env) File "/var/lib/ambari-agent/cache/common-services/AMBARI_INFRA_SOLR/0.1.0/package/scripts/infra_solr.py", line 49, in configure setup_infra_solr(name = 'server') File "/var/lib/ambari-agent/cache/common-services/AMBARI_INFRA_SOLR/0.1.0/package/scripts/setup_infra_solr.py", line 38, in setup_infra_solr group=params.user_group File "/usr/lib/ambari-agent/lib/resource_management/core/base.py", line 125, in __new__ cls(names_list.pop(0), env, provider, **kwargs) 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 199, in action_create recursion_follow_links=self.resource.recursion_follow_links, safemode_folders=self.resource.safemode_folders) File "/usr/lib/ambari-agent/lib/resource_management/core/providers/system.py", line 53, in _ensure_metadata raise Fail("User '{0}' doesn't exist".format(user)) resource_management.core.exceptions.Fail: User 'infra-solr' doesn't exist I google it, but i cannot find any solution.

I faced the same exception with Ambari 2.7.1 with different scenario. The scenario happens like that: I was trying to install Apache Solr with HDP Search as mpack. I wrongly installed the old version of mpack and when I restart the Ambari, Ambari couldn't open. I looked into ambari-server.log and the error was like below: An unexpected error occured during starting Ambari Server. com.google.inject.ProvisionException: Unable to provision, see the following errors: 1) Error injecting method, java.lang.NullPointerException at org.apache.ambari.server.api.services.AmbariMetaInfo.init(AmbariMetaInfo.java:250) at org.apache.ambari.server.api.services.AmbariMetaInfo.class(AmbariMetaInfo.java:123) while locating org.apache.ambari.server.api.services.AmbariMetaInfo for field at org.apache.ambari.server.controller.AmbariServer.ambariMetaInfo(AmbariServer.java:179) at org.apache.ambari.server.controller.AmbariServer.class(AmbariServer.java:179) while locating org.apache.ambari.server.controller.AmbariServer 1 error at com.google.inject.internal.InjectorImpl$2.get(InjectorImpl.java:1028) at com.google.inject.internal.InjectorImpl.getInstance(InjectorImpl.java:1054) at org.apache.ambari.server.controller.AmbariServer.main(AmbariServer.java:1101) Caused by: java.lang.NullPointerException at org.apache.ambari.server.stack.StackModule.mergeRoleCommandOrder(StackModule.java:1336) at org.apache.ambari.server.stack.StackModule.finalizeModule(StackModule.java:244) at org.apache.ambari.server.stack.StackManager.fullyResolveStacks(StackManager.java:413) at org.apache.ambari.server.stack.StackManager.<init>(StackManager.java:186) at org.apache.ambari.server.stack.StackManager$$FastClassByGuice$$33e4ffe0.newInstance(<generated>) at   I tried to start ambari-server as you said with --skip-database-check but it still couldn't open. Then I install the mpack with the same version before it down again, with this command:   sudo ambari-server install-mpack --mpack=/tmp/hdf-ambari-mpack-3.2.0.0-520.tar.gz --verbose   and I restart the ambari-server. Then ambari-server works without problem and I can access Ambari  from web. Perhaps it helps. ... View more
