What is the meaning of Anicca and Anatta? Most of the English translation I read, Anatta is translated as not-self and Anicca as impermanence.
However many Sri Lankan Buddhist monks do not agree with this translation.
They say it is a miss translation by Buddhagosha.
According to many Buddhist monks, it appears, Anicca means our inability to control the five aggregate. Anatta means the futile nature of the five aggregate. Is this true?
It is 'anatta' that means our inability to control the five aggregate, as found in the Pali as follows, where the word 'anicca' is not found at all:


  Rūpaṃ, bhikkhave, anattā. Rūpañca hidaṃ, bhikkhave, attā abhavissa, nayidaṃ rūpaṃ ābādhāya saṃvatteyya, labbhetha ca rūpe: ‘evaṃ me rūpaṃ
  hotu, evaṃ me rūpaṃ mā ahosī’ti. Yasmā ca kho, bhikkhave, rūpaṃ
  anattā, tasmā rūpaṃ ābādhāya saṃvattati, na ca labbhati rūpe: ‘evaṃ me
  rūpaṃ hotu, evaṃ me rūpaṃ mā ahosī’ti.
  
  Bhikkhus, form is nonself. For if, bhikkhus, form were self, this form would not lead to disease, and it would be possible to have it
  of form: ‘Let my form be thus; let my form not be thus.’ But because
  form is nonself, form leads to disease, and it is not possible to
  have it of form: ‘Let my form be thus; let my form not be thus.’
  
  SN 22.59


It is 'anicca' that means the futile nature ('dukkha') of the five aggregates, as also explained in SN 22.59:


  "What do you think of this, O monks? Is form permanent (niccaṃ) or
  impermanent (aniccaṃ)?"
  
  "Impermanent (aniccaṃ), O Lord (O Bhante)."
  
  "Now, that which is impermanent, is it unsatisfactory or
  satisfactory?"
  
  "Unsatisfactory, O Lord."
  
  "Now, that which is impermanent, unsatisfactory, subject to change, is
  it proper to regard that as: 'This is mine, this I am, this is my
  self (attā)'?"
  
  "Indeed, not that, O Lord."


Anatta (not-self) is the recognition that conditioned things (such as the five aggregates) do not belong to you (i.e., are not "mine") and cannot be an intrinsic permanent "you" (i.e., are not "me") due to their impermanent (anicca) nature.
