Difficulties to run reaper with postgresql backend

[Nicolas Charles]

Hello,

I'm trying to run cassandra-reaper with a postgresql backend.

Java crashes on a NullPointerException at start.

I'm running  with

reaper-1.5.0_BETA_20191018-1.x86_64

postgresql10-10.11-2PGDG.rhel7.x86_64

It seems that reaper is able to reach postgresql and store its data :

postgres=# \c reaper

You are now connected to database "reaper" as user "postgres".

reaper=# \dt

Below is last line of debug. Complete log is attached, and my reaper configuration yaml.

Reaper runs perfectly fine when using memory storageType.

Thanks for you help !

Hi,

this was fixed in Reaper 2.0.1, so you'll need to upgrade to get it working again.

Cheers,
