Description

If you override your JAVA_HOME to another location, the nifi.sh script will use it, but the RunNiFi launcher will ignore it entirely. This results in a failure with no logging (even with verbose flag) if your default Java version is too old. See an example below

# Check Java version
[cops@lannister-001 nifi-0.0.2-incubating-SNAPSHOT]$ java -version
java version "1.6.0_31"
Java(TM) SE Runtime Environment (build 1.6.0_31-b04)
Java HotSpot(TM) 64-Bit Server VM (build 20.6-b01, mixed mode)

# Override Java version
[cops@lannister-001 nifi-0.0.2-incubating-SNAPSHOT]$ export JAVA_HOME=/usr/java/jdk1.7.0_67-cloudera/

# Run NiFi (fails silently)
[cops@lannister-001 nifi-0.0.2-incubating-SNAPSHOT]$ ./bin/nifi.sh start -verbose

Java home: /usr/java/jdk1.7.0_67-cloudera/
NiFi home: /home/cops/nifi-0.0.2-incubating-SNAPSHOT

SEVERE: Apache NiFi does not appear to have started

Workaround: Edit the conf/boostrap.conf file and change the java command to the explicit JDK 1.7 path.

For example in my environment:

# Java command to use when running NiFi
java=/usr/java/jdk1.7.0_67-cloudera/bin/java

[cops@lannister-001 nifi-0.0.2-incubating]$ ./bin/nifi.sh run

Java home: /usr/java/jdk1.7.0_67-cloudera/
NiFi home: /home/cops/nifi-0.0.2-incubating
