Grant Henke commented on KUDU-2427:
-----------------------------------
We may want to break out the Java 9/10 compilation/test issues into another
Jira but I will list the known ones here for now:
* error-prone has an outdated compiler and because it replaces javac it needs
to be updated.
** https://github.com/google/error-prone/issues/860
* The gradle javadoc task is failing with `javadoc: error - invalid flag: -d`
** Not sure about this yet but I will look into it.
* KUDU-2403: We need to find a new way to prevent localhost dns in unit tests.
> Add support for Ubuntu 18.04

> Key: KUDU-2427
> URL: https://issues.apache.org/jira/browse/KUDU-2427
> Project: Kudu
> Issue Type: Bug
> Components: master, tserver
> Affects Versions: 1.8.0
> Reporter: Adar Dembo
> Assignee: Adar Dembo
> Priority: Major
>
> Ubuntu 18.04 (Bionic) is out, and since it's the next LTS release from Ubuntu
> we should support it. Unlike previous releases, this one is chock full of
> Kudu-breaking changes. It's getting difficult for me to keep track of them
> all, so I'll use this Jira to do that.
> h3. New Java
> Bionic ships with both JDK8 and JDK10, but defaults to JDK10. I'm sure
> that'll lead to a number of issues with our Java bindings. Most immediately,
> though, is [this cmake
> bug|https://gitlab.kitware.com/cmake/cmake/issues/17938] which prevents cmake
> from finding the JDK via find_package(Java). The bug fix is scheduled for
> 3.11.2 which has yet to be released; Bionic ships with a version of cmake
> 3.10 that has been patched to include this fix.
> h3. New gcc
> Bionic ships with gcc5, gcc6, gcc7, and gcc8, but defaults to gcc7. Beyond
> the usual set of new warnings, this version of gcc cannot compile breakpad.
> [This bug|https://bugs.chromium.org/p/google-breakpad/issues/detail?id=739]
> was filed, and it seems to have been fixed in the top of the breakpad tree,
> perhaps in [this
> commit|https://chromium.googlesource.com/breakpad/breakpad/+/bddcc58860f522a0d4cbaa7e9d04058caee0db9d].
> h3. New OpenSSL
> Bionic ships with libssl1.0 and 1.1, but defaults to 1.1. The transition from
> 1.0 to 1.1 [broke all sorts of ABIs and
> APIs|https://abi-laboratory.pro/tracker/objects_report/openssl/1.0.2o/1.1.0/report.html],
> some of which have been documented by KUDU-1889.
> h3. Miscellaneous stuff
> I'm still working through several test failures that I can't yet attribute to
> any one particular thing. These are:
> # Some tests that depend on libkudu_util.so appear to load that before
> loading libc, which causes the dl_iterate_phdr dlsym() call in
> util/debug/unwind_safeness.cc to fail at startup. Commenting that out leads
> to deadlocks in debug-util-test, so whatever underlying race existed in libc
> still exists.
> # All of the tests in minidump-test fail, probably due to changes in
> breakpad.
> # Symbolization via google::Symbolize appears to produce "(unknown)" frames
> in code that has been statically linked. Perhaps the problem is not so
> generic, but this leads to failures in stack_watchdog-test, which expects to
> find the name of the test in one of the stack frames.
