We didn't want to make deletion or modification of a shipped component
to be a required part of its installation since we don't produce the
NiFi download. We'd rather install it as it comes.

Ouch! It does happen on the loading of the NAR to ensure the native
library gets loaded. If you are not using Hive I’d think you could
safely delete the nifi-hive-nar and it shouldn’t happen. Hard to tell
why the native library couldn’t be installed though.

No, we don't even use (nor have we ever used) Hive in our flows.
It's just there and we didn't want to modify the NiFi download.
Should this not even happen if we're not using it?

Ugh now I remember, that version of Hive uses a version of Snappy
that doesn’t create a unique path under /tmp, do you have multiple
PutHiveStreaming processors in the flow? I don’t think that works
because we can’t load a single native library into multiple
classloaders.

I see

snappy-1.0.5-libsnappyjava.so
in //tmp/. Therefore, not a permissions issue? Launching this way
works:
$ ( export
LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/tmp/snappy-1.0.5-libsnappyjava.so"
&& /opt/nifi/bin/nifi.sh start )
but it's not something we want to do (in case that shared object
disappears from //tmp/).

IIRC this is likely a permissions issue, Xerial Snappy tries to
unzip the native library to the location pointed to by
“java.io.tempdir” which on *nix defaults to /tmp. Does the NiFi
user have write access to that directory? If not you can change
the Java temp dir or set it specifically for Snappy (I don’t have
the property on hand but a quick Google should find it)

Should I be seeing this in the log of a vanilla NiFi

"Snappy" makes me think Ubuntu. This is CentOS. Did I pull down
the wrong /nifi-1.11.4-bin.zip/?
