Problem

When trying to start the secondary hive metastore service, in this example, zookeeper is unable to create the znode with the appropriate permissions. This can be seen mostly on the non-Ambari managed clusters.

What to look for/Fix

The problem is usually due to the way zookeeper is configured. For instance, if zoo.cfg or zookeeper.env (java.env) in some cases have the following properties set

kerberos.removeHostFromPrincipal = true
kerberos.removeRealmFromPrincipal = true

then verify the ACL on the permission via zkCli.sh. In this example, my Zookeeper namespace for hive is set to "hahs2" so here is how the permission looks like

[zk: nodea.openstacklocal(CONNECTED) 1] getAcl /hahs2
'world,'anyone
: r
'sasl,'hive
: cdrwa

When the permissions are set to strip away the principal and "hive.cluster.delegation.token.store.zookeeper.acl" is not defined, the ACLs should look something like above. If this is not the case, then you would see the ACL set something like this

[zk: nodea.openstacklocal(CONNECTED) 1] getAcl /hahs2
'sasl,'hive/nodea.openstacklocal@HDP.COM
: cdrwa

These steps worked for me

  • Stop the hive server processes i.e. hive metastore and hiveserver2 instances
  • Login via zkCli.sh and try to remove the znode "rmr /hivedelegationMETASTORE" , if this gives error like "No Auth.." then you might need to modify any existence of the following properties to false. This could be there in java.env within /etc/zookeeper/conf or /apache/zookeeper/conf, based on your configuration
kerberos.removeHostFromPrincipal = false
kerberos.removeRealmFromPrincipal = false

  • Launch zkCli again and you should be able to delete the znode
  • Switch back the kerberos stripping properties to default and ensure there is only one place this is defined, either zoo.cfg or java.env (could be zookeeper-env.sh) in some scenarios
kerberos.removeHostFromPrincipal = true
kerberos.removeRealmFromPrincipal = true
  • Restart the Zookeeper servers (apply these changes to all the zookeeper servers)
  • Start one of the hivemetastore processes and check if the znodes are created with appropriate permissions i.e. shortnames like this
[zk: nodea.openstacklocal(CONNECTED) 1] getAcl /hivedelegationMETASTORE
'sasl,'hive
: cdrwa
  • If this is not the case then you might need to add the following in hive-site.xml for either hive instances
<name>hive.cluster.delegation.token.store.zookeeper.acl</name>
<value>sasl:hive:cdrwa</value>
  • Restart the hivemetastore and hiveserver2 processes. This should ideally have the ACLs with shortnames.
