I've heard the earlier theory (that it was an acronym for "Hierosolyma est perdita" which was supposed to have been a Crusader slogan), but Wiktionary thinks this is a false etymology.
I'm Ashkenazi Jewish and have never heard any Jewish or non-Jewish person claim to have personally associated the "hip hip hooray" cheer with antisemitism. Perhaps that association, even if it's etymologically incorrect, would have been top-of-mind for many Europeans in the 1820s, but I don't think that's so today.
Moreover, the same "hip-hip hooray" rally cry was used by the Red Army, who (while not specifically siding with Jewish people) liberated quite a number of people from the death camps.

Which Red Army? Unless it's the Chinese Red Army (which I have no knowledge about), but rather the Russian (Soviet) Red Army, then, firstly, the battle cry of its soldiers was not "hip-hip hooray", but rather "ura" (cognate of the English "hurrah"); and, secondly, this battle cry is much older than the Red Army. It's an old word; almost certainly a borrowing into Russian; but in which century (seventeenth? sixteenth? older?), and from which language, I do not know.
Well, this is the first time I hear "Hipp, hipp, Hurra" (the proper German version, since hurray is definetly not German) being linked to the Nazis and anti-semitism... And us Germans are rather sensitive about that
