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
