@Sindhu

Its on Metron alert ui log, but there is no error on Metron management and rest log. I just changed the port to 6k series now that error is resolve, but now the problem is different. Now the Metron service on my cluster is running with green, but Strom which Metron internally uses not able to read the Kafka topic, and there are no errors on any of the logs.

And can please suggest the version Metron that i can use with HDP 2.6.5.0 includes KAFKA 1.0.0 and Strom 1.1.0.

@Rajendra Manjunath

You can use Metron 0.4.2 with HDP 2.6.5 including Kafka 0.10.1 and Storm 1.1.0.

[#4]

My stacks are :

HCP 1.4.2.0 with Metron 0.4.1.4.2.0 i.e actually Metron 0.4.1

HDP 2.6.5.0-292

KAFKA 1.0.0

STROM 1.1.0

Should i have to downgrade the Kafka, if yes, Please suggest the way.
