URL: https://github.com/apache/pulsar/issues/7551
**Describe the bug**
Function if you use fat jar ${PULSAR_HOME}/instance/deps directory does not
work.
If a non fat jar is used, it will cause many problems.
For example,
1. Use a custom schema structure in the input and output types of the
function. This schema structure is in another jar, and it must be put into
${PULSAR_HOME}/lib directory, if the schema modifies the member variables, you
must restart functions worker;
2. When creating function, function jar must also be placed in
${PULSAR_HOME}/instance/deps directory can it be used normally. In this way,
from create function to run successful, the jar of fuction should have 3
copies:
1) function jar directory specified in bin/pulsar admin --jar
${FUNCTION_JAR_PATH};
2) ${PULSAR_HOME}/download directory;
3) ${PULSAR_HOME}/instance/deps directory;
which is too difficult to manage.
