----------------------------------------
Summary: ExternalSpillableMap throws ArithmeticException when
estimating the size of the payload
Key: HUDI-2718
URL: https://issues.apache.org/jira/browse/HUDI-2718
Project: Apache Hudi
Issue Type: Bug
Reporter: Manoj Govindassamy
Assignee: Manoj Govindassamy
Fix For: 0.10.0
When estimating the size of the payload, ExternalSpillableMap uses the current
in-memory map size, which could be zero and leading to Divide by Zero error
which in turn throws the ArithmeticException and crashing the callers.

long totalMapSize = ObjectSizeCalculator.getObjectSize(inMemoryMap);
this.currentInMemoryMapSize = totalMapSize;
this.estimatedPayloadSize = totalMapSize / inMemoryMap.size();
shouldEstimatePayloadSize = false;
LOG.info("New Estimated Payload size => " +
this.estimatedPayloadSize);{noformat}
