[GitHub] [pulsar] javard opened a new issue #6813: Function gets stuck in the context.getState() method
javard opened a new issue #6813:
URL: https://github.com/apache/pulsar/issues/6813
**Description**
When using the method *context.getState()* two times in a row sometimes it gets stuck in one of calls. When this happens and the function is restarted, the function always gets stuck launching (I think it can't connect to the bookkeeper) and Pulsar needs to be restarted.
**To Reproduce**
Steps to reproduce the behavior:
1. Multiple producers writing to *topic1*
2. Function inputs *topic1* and outputs to *topic2*
3. Function executes (in this order) :
3.1. *context.getState("key1")* and *context.getState("key2")* consecutively
3.2. *context.putState("key2")* and *context.putState("key1")* consecutively
3.3. returns a message
**Expected behavior**
*topic2* receives all the messages sent to *topic1*.
**Desktop:**
- OS: Ubuntu 19.10 64-bit
- CPU: Intel® Core™ i7-4770HQ CPU @ 2.20GHz × 4
- Memory: 10.5 GiB
**Additional context**
Pulsar version: 2.5.0
Command used to launch the function:
`./pulsar-admin functions localrun --jar path/to/jar/functions.nar --classname org.class.name.DummyFunction --tenant admin-tenant --namespace CHM --name dummy-function --inputs persistent://admin-tenant/CHM/topic1 --output persistent://admin-tenant/CHM/topic2 --processing-guarantees ATLEAST_ONCE --state-storage-service-url bk://localhost:4181 --broker-service-url pulsar://localhost:6650`

@sijie I think it's enabled. When I run in localrun without the flag `--state-storage-service-url` it throws the exception `java.lang.IllegalStateException: State is not enabled`.
But setting the flag (`--state-storage-service-url bk://localhost:4181`) the state storage works.
what is the correct way to enable the state storage?

@javard did you enable bookkeeper state storage?
