yuqi commented on CASSANDRA-13326:
----------------------------------
It is noted that JNA's pull request:
https://github.com/java-native-access/jna/pull/314.
Jna added support for AArch64 since version 4.2.0.
It is also appreciated that cassandra upgrade the jna version to 4.3.0.(
CASSANDRA-13300)
And I have create a ticket(CASSANDRA-13336) for upgrading snappy-java library
version up to 1.1.2.x, which added support for AArch64 but version1.1.1.7 did
not.
