You are probably running out of space on disk or the limits for your NiFi repository are being reached.

Have a look at the article below and try to reduce retention and/or increase the available repository space.

Hello Zhangliang,

For the more efficient tuning of the content repository archive you can use these pages (you might have already known them):
https://community.cloudera.com/t5/Community-Articles/Understanding-how-NiFi-s-Content-Repository-Arc...
https://nifi.apache.org/docs/nifi-docs/html/nifi-in-depth.html#deeper-view-provenance-log-files

also 

1] - Add the following property from Ambari under nifi.properties section to a value of 75%
nifi.content.repository.archive.backpressure.percentage to 75%

2] Increase the disk space.
