Hi Kannan, We are building / testing / running ZooKeeper in production using CentOS 7.5 among other linux versions, so 7.5 should definitely work. Although I am not sure about CentOS 7.
Do you actually need to run the tests? If not, then you can use the following command to skip the test executions: mvn clean install -DskipTests or if you also need the native libraries: mvn clean install -DskipTests -Pfull-build Also, if you think the tests are flaky in your case, you can ask maven to try them more times: mvn -Dsurefire.rerunFailingTestsCount=3 test -fae I use to build ZooKeeper many times in docker on my macbook pro, using an official CentOS 7.5 image. These are my steps: ``` docker run --volume ~/git:/git -it --rm centos:7.5.1804 /bin/bash # then inside docker I install all the dependencies I need (also everything for the native C library builds and the zkpython build) yum -y install autoconf automake mc git maven java cppunit python-setuptools screen libtool python-devel cppunit-devel gcc-c++ telnet openssl openssl-devel # if you also need SASL for the C client (only available on the master branch) yum -y install cyrus-sasl-md5 cyrus-sasl-gssapi cyrus-sasl-devel cd /git/zookeeper # this gives you a clean state, if you use git (not needed if you just downloaded the source tarball) git clean -xdf # full build incl. native C code, skipping the tests mvn clean install -Pfull-build -DskipTests ``` On Fri, Jan 24, 2020 at 8:52 AM KANNAN VARADHAN <kan...@ieee.org> wrote: > Hi Marnix: > > My initial selinux state was “Permissive”. > I rebooted with selinux disabled, and did the build.
