> Ambari checks fail with FIPS mode is activated on the OS (Rhel7). FIPS mode disables weak ciphers (such as MD5).
> Ambari code is doing
> {code}
> ccache_file_name = _md5("
> {0}|{1}".format(principal, keytab)).hexdigest(). MD5 is disabled on the OS (RHEL7) so ambari throws errors.
> {code}
> - All service checks fail, Ranger KMS start fails via ambari.
> - However all the services are actually running and fine.
> - Also Ranger KMS succesfully started from command Line
> Here is the stack trace from Ambari
> {code}
> service_check
> params.kinit_path_local, False, None, params.smoke_user)
> File "/usr/lib/python2.6/site-packages/resource_management/libraries/functions/curl_krb_request.py", line 109, in curl_krb_request
> ccache_file_name = _md5("{0}
> |
> {1}
> ".format(principal, keytab)).hexdigest()
> ValueError: error:060800A3:digital envelope routines:EVP_DigestInit_ex:disabled for fips
> {code}
> Fix:
> MD5 is disabled on the OS, Code needs to be updated to use SHA?
> This is required when FIPS mode is enabled on the RHEL OS
