After restarting Pivot to pick up Marcel's banner_activity_minutely_sanitization_test cleanup we noticed that the pageviews hourly data is not showing up. Pivot started to log a weird patter of auto-discovery from May 2nd:
May 2 22:03:44 thorium pivot[57590]: Got the latest time for 'pageviews-hourly' (2017-05-02T22:00:00.000Z) May 2 22:04:39 thorium pivot[57590]: Cluster 'druid' could not introspect 'pageviews-hourly' because: null exception May 2 22:04:45 thorium pivot[57590]: Got the latest time for 'pageviews-hourly' (2017-05-02T22:02:00.000Z) May 2 22:04:45 thorium pivot[57590]: Got the latest time for 'pageviews-hourly' (2017-05-02T22:02:00.000Z) May 2 22:05:45 thorium pivot[57590]: Got the latest time for 'pageviews-hourly' (2017-05-02T22:04:00.000Z) May 2 22:05:45 thorium pivot[57590]: Got the latest time for 'pageviews-hourly' (2017-05-02T22:04:00.000Z) May 2 22:06:39 thorium pivot[57590]: Cluster 'druid' could not introspect 'pageviews-hourly' because: null exception May 2 22:06:45 thorium pivot[57590]: Got the latest time for 'pageviews-hourly' (2017-05-02T22:06:00.000Z) May 2 22:06:45 thorium pivot[57590]: Got the latest time for 'pageviews-hourly' (2017-05-02T22:06:00.000Z) May 2 22:07:45 thorium pivot[57590]: Got the latest time for 'pageviews-hourly' (2017-05-02T22:07:00.000Z) May 2 22:07:45 thorium pivot[57590]: Got the latest time for 'pageviews-hourly' (2017-05-02T22:07:00.000Z) [..]
After the last pivot restart we got also another error message:
