User hbase is not allowed to impersonate hue

Hello,

When trying to access Hbase through Hue i have this error in the log

WARN org.eclipse.jetty.server.HttpChannel: handleException / org.apache.hadoop.security.authorize.AuthorizationException: User: hbase is not allowed to impersonate hue

knowing that i had set a Thrift Server instance on Hbase and it is running okay.

@raniaa You need to allow HBase impersonation in HDFS for HBase Browser to work. Here are the steps: https://docs.cloudera.com/documentation/enterprise/latest/topics/admin_hdfs_proxy_users.html

In summary you need to:

1. Enable hbase.thrift.support.proxyuser. CM > HBase > Configuration > Search: "hbase.thrift.support.proxyuser"
2. Allow all groups form all hosts in HDFS. 
CM > HDFS > “Cluster-wide Advanced Configuration Snippet (Safety Valve) for core-site.xml”
hadoop.proxyuser.hbase.hosts
*
hadoop.proxyuser.hbase.groups
*

Thank you @GangWar i tried these steps before and turns out that i had been modifying these parameters in the wrong core-site.xml file , it works just fine now 😉
