Thanks @ Artem and @ Dileep Kumar. I have re-installed VMWare and it has fixed the issue.

Check whether namenode is in standby, make sure all services are up.

@Pavani N Check the following params

core-site.xml

 <property>
      <name>hadoop.proxyuser.<loginuser>.hosts</name>
      <value>*</value>
 </property>
 <property>
      <name>hadoop.proxyuser.<loginuser>.groups</name>
      <value>*</value>
 </property>

hdfs-site.xml

<property>
     <name>dfs.webhdfs.enabled</name>
     <value>true</value>

Hi!

I got the same error here.

I followed all the instructions here :

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.0/bk_installing_manually_book/content/configu...

All the Hive Servers in Ambari : WebHCat, Hive Metastore and HiveServer2 are up.

I checked the properties in core-site.xml and hdfs-site.xml as @Dileep Kumar Chiguruvada said

When I click on Beewax in Hue I still get Error! Could not connect to http://sandbox.hortonworks.com:10000

Does anyone know how to overcome this issue?
