This might help to other people. This seems like a bug : https://issues.apache.org/jira/browse/AMBARI-21687 The bug is fixed in 2.6.0.0 branch only ( not fixed in 2.4.x.x or 2.5.x.x versions of ambari). So, The available workaround is to add the node via 'Admin' user or use the ambari 2.6.x

You can try adding this "hadoop.ssl.enabled.protocols" property in custom core-site in ambari->HDFS service. See [1] for information on this property : [1] https://hadoop.apache.org/docs/r2.7.2/hadoop-project-dist/hadoop-common/core-default.xml

@Michael Bronson See this link http://henning.kropponline.de/2015/06/07/services-and-state-with-ambari-rest-api/which would helps.

Yes, that's correct. Hortonworks does not support the fair scheduler and it's not suggested to use this in production. See [1] [1] https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.3/bk_release-notes/content/community_features.html

@Jacqualin jasmin See if you are also facing the warning defined in link [1]. If yes, try the same resolution.

In what scenario we have to choose the binary type or string type in ORC table? It my understanding that, we have to use the type as binary when the datatype string value is more than > 2Gb and If it's below than 2GB then we can go for string data type. Is that correct? I've already seen this : https://orc.apache.org/docs/encodings.html When we use string type value less than 2GB, getting below error but when switched to binary it's working as expected. Any idea what could be the cause. " java.lang.RuntimeException: java.io.IOException: com.google.protobuf.InvalidProtocolBufferException: Protocol message was too large. May be malicious. Use CodedInputStream.setSizeLimit() to increase the size limit. "

@sulanta thanks but my requirement is little different. What I want is to restrict the user from dropping the database but that user should be able to drop the table. Is this possible?

- Is it possible to DROP TABLE but not DROP DATABASE in Hive using Ranger Hive Plugin on latest version of HDP?

@hari Kishore javvaji Dr.who is the default username/static for hadoop core property : "hadoop.htttp.staticuser.user" The description say's : The user name to filter as, on static web filters while rendering content. An example use is the HDFS web UI (user to be used for browsing files) See this: [1] http://hadoop.apache.org/docs/r2.8.0/hadoop-project-dist/hadoop-common/core-default.xml Hope this answered your question.

@Sara Alizadeh Did you mean after enabling maintenance mode on namenode, you can not edit the config changes from ambari ? Please note Without enabling maintenance mode you can change the java heap size. Please see article [1] which talks on how to set namenode heap size. Also, see thread [2] which also talks on same.

- Is there any way using which we can get the list of user who submitted the Job in the specific queue? Eg : 1) If I am having queue as 'myQueue' then List all user who submitted the Job to 'myQueue' 2) List all user who submitted the specific type of Job : eg List all user who submitted only Hive Job in 'myQueue'.
