Ambari 2.5.0.3 install HDF Nifi

Tried to install Nifi using Ambari.

Got error message:

File “/var/lib/ambari-agent/cache/common-services/NIFI/1.0.0/package/scripts/params.py”, line 47, in <module> stack_version_buildnum = get_component_version_with_stack_selector(“/usr/bin/hdf-select”, “nifi”) NameError: name ‘get_component_version_with_stack_selector’ is not defined

 

All hosts in Ambari Hosts menu showed Stack: HDP, Name: HDP-2.6.1.0, Status: Current.

 

Could not resolve it via Ambari. Even hdf-select in node where to I tried to install Nifi I cot executing:

hdf-select

nifi – 3.0.0.0-453

Solution for me was to change some lines in /var/lib/ambari-agent/cache/common-services/NIFI/1.0.0/package/scripts/params.py. Commented out red line and added green:

 

if stack_name == “HDP”:

  # Override HDP stack root

  stack_root = “/usr/hdf”

  # Override HDP stack version

  #stack_version_buildnum = get_component_version_with_stack_selector(“/usr/bin/hdf-select”, “nifi”)

  stack_version_buildnum = get_component_version(stack_name, “nifi”)

elif not stack_version_buildnum and stack_name:

  stack_version_buildnum = get_component_version(stack_name, “nifi”)
