Aleksandr Efimov commented on IMPALA-12955:
-------------------------------------------
I'm taking a look at this.
I have a local prototype that links impala-profile-tool against a narrower set
of backend objects instead of the full backend link set. In my local build this
removes the unused runtime dependencies listed in the Jira, including JVM, Kudu
client, SASL/Kerberos and OpenSSL libraries, while keeping the profile-tool
tests passing.
The refactor still needs some cleanup and validation before I post a Gerrit
change.
