Access Hadoop with kerberos failed -


i install hadoop , kerberos, but when exec hadoop fs -ls / error has bean occured.

[dannil@ozcluster06 logs]$ hadoop fs -ls / 16/09/13 11:34:39 warn ipc.client: exception encountered while connecting server : javax.security.sasl.saslexception: gss initiate    failed [caused gssexception: no valid credentials provided (mechanism level: failed find kerberos tgt)] ls: failed on local exception: java.io.ioexception: javax.security.sasl.saslexception: gss initiate failed [caused gssexception: no valid credentials provided (mechanism level: failed find kerberos tgt)]; host details : local host is: "localhost/127.0.0.1"; destination host is: "192.168.168.46":9000;

i can see datanode , namenode has start jps

  20963 datanode   21413 secondarynamenode   20474 namenode   22906 jps

i add principal hdfs/oz.flex@oz.flex , http/oz.flex@oz.flex,then use xst -norandkey -k hdfs.keytab hdfs/oz.flex@oz.flex http/oz.flex@oz.flex generate hdfs.keytab

kadmin.local:  listprincs http/oz.flex@oz.flex k/m@oz.flex dannil/admin@oz.flex hdfs/oz.flex@oz.flex kadmin/admin@oz.flex kadmin/changepw@oz.flex kadmin/ozcluster06@oz.flex kiprop/ozcluster06@oz.flex krbtgt/oz.flex@oz.flex

then exec kinit -kt /home/dannil/hadoop-2.7.1/hdfs.keytab hdfs/oz.flex

i can see ticket status :

[dannil@ozcluster06 ~]$ klist ticket cache: keyring:persistent:1000:krb_ccache_4h73pla default principal: hdfs/oz.flex@oz.flex  valid starting       expires              service principal 2016-09-13t10:47:06  2016-09-14t10:47:06  krbtgt/oz.flex@oz.flex

this hadoop config value:

core-site.xml:

hdfs-site.xml:
