Hello Champions

   I am experiencing "HeapDumpOnOutOfMemoryError"  issue, kafka fails to start. I tired with increasing broker memory size from 1 GIB to 8 GIB gradually, but didn't worked out. I checked with the cloudera documentation of it says incompatible java-version cloud lead to this error, It is working with different version of kafka. Kafka ends with supervisor FATAL Error. Please help me in fix this.

   1. CDH-5.16.1

   2. KAFKA-4.0.0-1.4.0.0.p0.1 

   3. oracle-j2sdk1.7-1.7.0+update67-1

   4. referred documentation url
