Hi, We can't help with the HBase thing, for that you need to chase the HBase user ML.
For the `hadoop checknative -a` showing false, maybe the native libraries that are pre-built & published aren't compatible with the OS you are using, In that case you need to build them on the "same" OS, the instructions are here: [1] & replace those generated native files with the existing ones. Second, Run the command `hadoop jnipath` and see the output path & check you have the native libs in that directory. If both of the above things don't work then enable debug logging & then run the checknative command and capture the log & exception as here [2] & they might give you an answer why the native libraries aren't getting loaded. Most probably solving the Hadoop stuff should dispel the HBase or any downstream problem tethered to native libs. -Ayush [1] https://hadoop.apache.org/docs/stable/hadoop-project-dist/hadoop-common/NativeLibraries.html#Build [2] https://github.com/apache/hadoop/blob/1baf0e889fec54b6560417b62cada75daf6fe312/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/util/NativeCodeLoader.java#L52-L55 On Sat, 25 May 2024 at 18:58, <fe...@posteo.nl> wrote: > > Hi all, > > Using hadoop 3.3.6, hbase 2.5.6, and jdk 11 on EL9 we're seeing an > UnsatisfiedLinkError when running the NativeLibraryChecker.
