Subject: Not enough data to calculate spout lag
Hi,
I found log "Metrics Tick: Not enough data to calculate spout lag." in my
topology and then topology becomes inactive.
I check the source:
if (_partitions != null && _partitions.size() == _partitionToOffset.size()) {
......}else {
LOG.info("Metrics Tick: Not enough data to calculate spout lag."); }
What situation will cause _partitions != null or _partitions.size()
==_partitionToOffset.size()?
Thanks,
Sachin
