---------------------------------------
Summary: FlowRunEntity does not deserialize long values in
efficient way.
Key: YARN-6074
URL: https://issues.apache.org/jira/browse/YARN-6074
Project: Hadoop YARN
Issue Type: Sub-task
Components: timelinereader
Reporter: Rohith Sharma K S
Assignee: Rohith Sharma K S
I see that FlowRunEntity methods *getRunId()* and *getMaxEndTime()* does not
deserialize in efficient way which causes class cast exception based on the
number.
{code}
public long getRunId() {
Object runId = getInfo().get(FLOW_RUN_ID_INFO_KEY);
return runId == null ? 0L : (Long) runId;
}
{code}
and
{code}
public long getMaxEndTime() {
Object time = getInfo().get(FLOW_RUN_END_TIME);
return time == null ? 0L : (Long)time;
}
{code}
The reason for class caste exception is Json has data type Number which
includes all java primitive types. So, if number with in the range of Integer
max, then Object is converted to Integer which fails to type cast to Long.
