Does HDP 3.0.1 support Superset 0.35 with Python 3...

Hello, We use HDP 3.0.1 and know that HDP 3.0.1 supports Python 2.7.x. We use Superset for  visualization and need to implement some extra features for Superset. So that we want to use the latest version of the Superset (0.35.2) with Python3. We wonder that does HDP 3.0.1 supports the latest version of Superset? Could we execute Superset (0.35.2) with Python3 from a different environment? The other services will use the same Python2 version as before, but only Superset will use the Python3. Is this possible? Will this situation cause any problem for other services like Hive, Druid etc. ? ... View more

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

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

Error in the Druid documentation

Hello,   While I'm installing and trying to Druid, I realized that there is a mistake in the document and this mistake causes the error. On this page  https://docs.cloudera.com/HDPDocuments/HDP3/HDP-3.0.1/adding-druid/content/druid_query_druid.html  in step one, it said to create a file and named as wickiticker-top.json. But in step 2, when the HTTP query is made, the name of the file is written as wikiticker-top.json. Yesterday I'm trying to execute this command and it gave me an error. Then I realized that the name of the file is written wrongly. After I edit the name of the file, everything is worked as I expected but this situation took my time. To avoid other people having the same problem, it should be edited as soon as possible.   For your information. ... View more
