Metron always can run normally first,but after some while,no data shows on kibana.And errors show as follow:
like screenshot shows ,no data reaches hdfsindexingbolt and indexingbolt.
Any help will be appreciated!
Can you provide more information about your environment? Is this vagrant full, quick, bare metal, etc.? Also, what data are you sending in? Is it getting parsed and enriched, but not indexed or something else?
Three physical machine for hdp, one physical machine for sensor.And i am sure data is parsed and enriched. Also i can find data in elasticsearch .
Data appears to be getting there, just not leaving there (which is correct as data only is emitted from the indexing bolts if there's an error and there have been no errors thusfar. Can you check the indices and make sure there's data? I suspect you'll find some.
Thanks @leo lee
Yes, data should be getting to Elasticsearch, there are no errors/failures in the topology (based on your screenshot above)
To your question about the significance of color in Storm Topology visualization, it's showing relative load / performance of different bolts. The HDFS Indexing Bolt consumes a lot more time (75.776 ms) compared to other bolts.
