Rohith Sharma K S updated YARN-6074: ------------------------------------ Attachment: YARN-6074.patch Updated patch by type casting to Number and getting long value. > 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 > Attachments: YARN-6074.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
