innobackupex does not catch error correctly

[shinguz]

innobackupex does not catch error correctly when user is not specified or privileges are not correct and starts to hang in log scan loop forever.

IMHO we should do a proper exit there with a bit more verbose error message there: which user was tried where were we looking for:

xtrabackup v2.1.3

hangs in endless loop?

Oli,

Yes, that's a known problem also reported and discussed in bug #1135441. Closing this one as a duplicate.
