kinit: Password incorrect while getting initial credentials

[#1]

i use kadmin to generate impala principal keytab(it previous generated by cloudear manager), now impala start failed even though new keytab generated by Cloudera Manager.

in cdh admin page error is: unable to login from keytab: Decrypt integrity check failed

use kinit in command line error is: kinit: Password incorrect while getting initial credentials

any help will really appreciated.

i fixed this by the step:

    move all directory include impala.keytab on the error node to a bak derectory

    regenerate the principal from chd admin page

    restart impala on chd admin page
