Hi,
I've noticed in the logs that Accumulo native library is not available:
TabletServer_1410060415.out:307:2021-12-08T14:09:24,257 [tserver.NativeMap]
ERROR: Tried and failed to load Accumulo native library from
/home/ubuntu/git/accumulo/server/native/target/accumulo-native-2.1.0-SNAPSHOT/accumulo-native-2.1.0-SNAPSHOT:/usr/java/packages/lib:/usr/lib/aarch64-linux-gnu/jni:/lib/aarch64-linux-gnu:/usr/lib/aarch64-linux-gnu:/usr/lib/jni:/lib:/usr/lib
Initially I thought that it might be an issue related to ARM64 and I
checked the build of server/native:
]

says: #include "org_apache_accumulo_tserver_NativeMap.h"
but there is no such file in the same folder!
There is
https://github.com/apache/accumulo/blob/2fd40dd8fd68c94bad6fb887d6b1cd99d39481c3/server/native/src/main/c%2B%2B/nativeMap/NativeMap.h
i.e. the include must be just "NativeMap.h", right ?!
But even after fixing this it still fails:

The method names are JNI namespaced.
How is this supposed to work ?
Cheers,
