How to disable Hadoop Kerberos

问题

I used a internal script to setup a Hadoop cluster. It configured Hadoop security with Kerberos by default. This is very inconvenient for a developing environment.

I googled a lot, but the results are all about "how to enable ...".

Please help to give some reference or advice.

回答1:

Change the values for:

core-site.xml(HDFS):

hadoop.security.authentication to simple
hadoop.security.authorization to false

hdfs-site.xml(HDFS):

dfs.datanode.address to 50010
dfs.datanode.http.address to 50075

hbase-site.xml(HBASE):

hbase.security.authentication to simple
hbase.security.authorization to false
Comment these properties if present: hbase.regionserver.kerberos.principal, hbase.regionserver.keytab.file, hbase.master.kerberos.principal, hbase.master.keytab.file, hbase.rpc.engine.

zoo.cfg:

Comment these line if present: kerberos.removeHostFromPrincipal=true, kerberos.removeRealmFromPrincipal=true

Permission:

Change the HDFS data directory permission to 755. Search for dfs.data.dir in hdfs-site.xml.

Do these changes on all nodes. Restart your cluster and check if its disabled.

Rajesh N has suggested to change the values in properties; But simply commenting those properties and restart the cluster will result in Simple cluster; When you want to enable security back, simply you can uncomment the same properties and restart the cluster;
