Kerberos - javax.security.sasl.SaslException. Client mechanism is malformed

[xjg2010go]

hi I'm a beginer for using snakebite. when I exec " snakebite -D ls / ",It works.It turn out like this: [root@sjs_38_58 src]# snakebite -D ls /

DEBUG:snakebite.config:Got namenode 'hdfs://bizclustertest' from /opt/local/bizhadoop/hadoop/etc/hadoop/core-site.xml DEBUG:snakebite.config:Got hadoop.security.authentication 'kerberos' DEBUG:snakebite.config:Got namenode '//rsync.nn1.bizclustertest.zw.ted:8020' from /opt/local/bizhadoop/hadoop/etc/hadoop/hdfs-site.xml DEBUG:snakebite.config:Got namenode '//rsync.nn2.bizclustertest.sjs.ted:8020' from /opt/local/bizhadoop/hadoop/etc/hadoop/hdfs-site.xml DEBUG:snakebite.config:hdfs principal found: 'biztech/[email protected]' DEBUG:snakebite.client:Switch to namenode: rsync.nn1.bizclustertest.zw.ted:8020 DEBUG:snakebite.client:Created client for rsync.nn1.bizclustertest.zw.ted:8020 with trash=True and sasl=True ....

when I use it in ipython like this:

from snakebite.client import Client client = Client("rsync.nn1.bizclustertest.zw.ted", 8020, use_trash=True,use_sasl=True) for x in client.ls(['/']):
print x ..... RequestError: javax.security.sasl.SaslException Client mechanism is malformed

It does not work. when I look up the manual doc, I find this parameter, "hdfs_namenode_principal", what should I set it? The hdfs authentication use Kerberos.

I have same issue and install those packages: sudo apt-get install cyrus-sasl2-mit-dbg libsasl2-modules-gssapi-mit refer to https://launchpad.net/ubuntu/+source/cyrus-sasl2 Hope it will work.
