Hey,
Recently I used flink1.6.3 to run a task and the following exception
occurred. Can someone tell me how to solve this problem?
AsynchronousException{java.lang.Exception: Could not materialize checkpoint
10631 for operator Source: Custom Source -> Flat Map -> (Map ->
Timestamps/Watermarks -> from: (dtEventTime, bkdata_par_offset, N_Route,
iEventId, vVersion, vFromIp, vLocalIp, iRequestType, vAppid, vOpenid,
vCmdid, vL5_ip_port, iPermission, iResult, dProcessTime, vErrorMsg, vUrl,
vDeviceInfo, rowtime) -> where: (OR(=(iResult, -308), =(iResult, -309))),
select: (rowtime, vErrorMsg) -> time attribute: (rowtime), Map) (8/20).}
