ubuntu - Failing to add host in Ambari server -


i using single machine set ambari server, can install hadoop. lot of sites referred to. error getting while registering node is:

creating target directory... ==========================  command start time 2017-07-26 14:50:10  permission denied (publickey). ssh command execution finished host=shubham-r528-r728, exitcode=255 command end time 2017-07-26 14:50:11  error: bootstrap of host shubham-r528-r728 fails because previous action finished non-zero exit code (255) error message: permission denied (publickey).  stdout:  permission denied (publickey).

enter image description here

i have 

shubham@shubham-r528-r728:~$ hostname -f shubham-r528-r728 shubham@shubham-r528-r728:~$

i follow http://linux-sys-adm.com/how-to-install-and-configure-ssh-on-ubuntu-server-14.04-lts-step-by-step/ on root account set ssh key.

the following steps required setting cluster amabari:

  1. setting passwordless ssh
  2. letting ambari make use of this

the symptoms see occur in part 2, judging comment root cause of problem in part 1.

the news when problems not hadoop specific, see typically more people run them, , post solutions.

i not sure whether helps in case (as doing things root), quick search failing add host led me this question, indicated there may right issue on relevant ssh file.

just thinking out of box: if problem host cannot added known hosts file, perhaps can add manually somehow.

transpose - Maple isnt executing function but prints function term -

im using maple im in worksheetmode tried using maple input , 2d input , want transpose matrix a: := `<|>`(`<,>`(1, .5, -2), `<,>`(.5, 9/4+b, 5+3*b), `<,>`(-2, 5+3*b, 18+9*b+4*a)); b:= transpose(a); when exectute sheet dont translated values, there same input. matrix looks same input matrix plus function term. you can see picture in following link: why arent functions executed? meanwhile b:=a^+ doing right way , transposed matrix. other functions return function body instead needed values... if using 2d input mode (the default) space you've got between transpose , bracketed (b) interpreted multiplcation. rid of such space. also, either load package @ start of document like, with(linearalgebra): before calling transpose command package, or call it's full name like, linearalgebra:-transpose(b);
