Is that why many Buddhists claim Jesus to be an enlightened master?
He is usually considered to be a Bodhisattva, not a Buddha. The precise meaning of Bodhisattva varies between the Theravada and Mahayana. The Theravada version is closer to a very holy man. The Mahayana version has many of the attributes of a god. Of course, gods can be Buddhists and themselves attain enlightenment.
Also, the reason I asked the OP question was because Buddha is always talked about becoming one with the Dharma. I figured that would mean he becomes omniscient since he is becoming one with the Truth. I’ve also seen some Buddhists claim he is omniscient, so I’m not really sure what to believe about it.
I have seen that too. I have also seen a text which says that the Buddha did not know everything, but he did know whatever he needed/wanted to know. Being a Buddha he was not interested in useless knowledge, only in useful knowledge. He had all useful knowledge available to him.
This from the Pali Canon:
[Vacchagotta said:] I have heard it said that the recluse Gotama is allknowing and all-seeing, with nothing outside his ken and vision, and that he claims that, whether he is walking or standing still, whether he is asleep or awake, his ken and vision stand ready, aye ready.
Pray, sir, is this witness true, not misrepresenting the Lord and not mis-stating the gist of his Doctrine?
[The Buddha said:] The witness, Vaccha, is not true; it imputes to me what is false and untrue.
[Vacchagotta:] Well, sir, what account ought we to give of the Lord, so as not to misrepresent him or misinterpret the gist of his Doctrine or entail the censure of an orthodox expositor thereof?
[Buddha:] He would bear true witness, neither misrepresenting me nor misinterpreting the gist of my Doctrine nor entailing the censure of an orthodox expositor thereof, - who should say:
The recluse Gotama has the threefold lore (te-vijja).
For, Vaccha,
(i) as long as I please, I can call to mind all my own past existences, from a single one onwards, in all their details and features,
(ii) As long as I please, I can see - with the Eye Celestial, which is pure and far surpasses the eye of man - creatures in act to pass hence and re-appear elsewhere (etc., as in Sutta No. 4),
(iii) By destroying the Cankers, I have won that Deliverance of heart and mind in which no Cankers are; here and now have I entered on and abide in this Deliverance, which of and by myself I have discerned and realized.
So it would be a true witness, Vaccha, to say that I have the threefold lore.

My apologies for the old translation, I could not find a more recent one on the web.
The Buddha had much knowledge, but he was not omniscient.
