> hive sink not sending heartbeat correctly
> -----------------------------------------
>
> Key: FLUME-2956
> URL: https://issues.apache.org/jira/browse/FLUME-2956
> Project: Flume
> Issue Type: Bug
> Components: Sinks+Sources
> Affects Versions: 1.5.2
> Environment: linux CentOS 6.6
> Reporter: Olivier brobecker
> Attachments: flume-hive-sink-1.8.0.jar, hive-sink-patch.txt

> Flume has been configured in order to populate a hive table as follow :
> agentSCDR.sinks.hive1.type = hive
> agentSCDR.sinks.hive1.channel = channel1
> agentSCDR.sinks.hive1.hive.metastore = thrift://myserver:9083
> agentSCDR.sinks.hive1.hive.txnsPerBatchAsk = 10
> agentSCDR.sinks.hive1.hive.database = myDatabase
> agentSCDR.sinks.hive1.hive.table = my_table
> agentSCDR.sinks.hive1.hive.partition = %Y
> agentSCDR.sinks.hive1.heartBeatInterval = 60
> agentSCDR.sinks.hive1.serializer = DELIMITED
> agentSCDR.sinks.hive1.serializer.delimiter = ;
> agentSCDR.sinks.hive1.serializer.serdeSeparator = ;
> agentSCDR.sinks.hive1.serializer.fieldnames = field1,field2,field3...
> My dataflow is irregular at best and I can have more than 30 minutes of
> inactivity, so I have a heartbeatInterval at 60s in order to keep my txn
> alive.
> The issue is that this heartBeat is only sent when flume is trying to inject
> some datas into hive instead of having one every 60s.
> # grep -i heartbeat flume-agentSCDR.log
