java - Found unsupported keytype (8) for Principal -

i using java 7 , kerberos authenticate hadoop.

in debug log seeing next error:

ordering keys wrt default_tkt_enctypes list default etypes default_tkt_enctypes: 23 18 17 16 3 1. added key: 3version: 1 **found unsupported keytype (8) hdfs/aaa.aaa@example.com** added key: 23version: 1 added key: 16version: 1 added key: 17version: 1 added key: 18version: 1

how right error?

sorry it's bit late, i've encountered missing local_policy.jar , us_export_policy.jar files in directory: $java_home/jre/lib/security/.

other times, mis-configured krb5.ini file.
