Ricky Saltzer created NIFI-416:
----------------------------------
Summary: NiFi launcher does not respect JAVA_HOME, fails silently
Key: NIFI-416
URL: https://issues.apache.org/jira/browse/NIFI-416
Project: Apache NiFi
Issue Type: Bug
Reporter: Ricky Saltzer
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
{code}
# 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

SEVERE: Apache NiFi does not appear to have started
{code}
*Workaround*: Edit the _conf/boostrap.conf_ file and change the java command to
the explicit JDK 1.7 path.
For example in my environment:
{code}
# Java command to use when running NiFi
java=/usr/java/jdk1.7.0_67-cloudera/bin/java
{code}
{code}
