MiNiFi on Raspberry fails to start after crash

Former Member — Wed, 16 Nov 2016 05:45:14 GMT

I am running MiNiFi 0.0.1 (Java) on a Raspberry Pi 2 Model B. Recently, the Raspberry was rebooted after a power outage but I could not bring up MiNiFi again. The log looks like this:

What happened here? I am looking for ideas how to

fix this
prevent startup problems in the future.

Apparently this is a known issue: https://issues.apache.org/jira/browse/NIFI-2890.

I deleted all files in provenance_repository/journals/ - after that MiNiFi started up fine.

For me it was the config.yml which I was generated with some other name earlier, like - xxxx.yml , whereas it should be config.yml instead.

After that my minifi getting started normally. Hope it will help few.
