Hi Arnaud, I’m sorry you are having trouble getting NiFi going. We want to minimize any inconvenience and get you up and running quickly.
Are you by any chance running on a VM that does not have access to any physical inputs to generate entropy for secure random seeding? There is a known issue [1] (being worked on for the next release) where this can cause the application to block because insufficient entropy is available (without the physical inputs, there is not enough random data to properly seed secure operations). I recommend you check if this the case (run this command in your terminal — if it hangs, this is the cause): head -n 1 /dev/random If it hangs, follow the instructions on this page [2] to modify the Java secure random source (ignore the warning that this is “less secure” — this is an urban legend propagated by a misunderstanding in the Linux kernel manual pages [3]). Modify $JAVA_HOME/jre/lib/security/java.security to change securerandom.source=file:/dev/random to securerandom.source=file:/dev/urandom [1] https://issues.apache.org/jira/browse/NIFI-3313 <https://issues.apache.org/jira/browse/NIFI-3313> [2] https://docs.oracle.com/cd/E13209_01/wlcp/wlss30/configwlss/jvmrand.html <https://docs.oracle.com/cd/E13209_01/wlcp/wlss30/configwlss/jvmrand.html> [3] http://www.2uo.de/myths-about-urandom/ <http://www.2uo.de/myths-about-urandom/> Andy LoPresto alopre...@apache.org alopresto.apa...@gmail.com PGP Fingerprint: 70EC B3E5 98A6 5A3F D3C4 BACE 3C6E F65B 2F7D EF69 > On Feb 15, 2017, at 1:29 AM, Arnaud G <greatpat...@gmail.com> wrote: > > Hi guys! > > I'm trying to play with nifi (1.1.1) in a docker image.
