我的程序可能出错的地方就是在flatmap里面用了一个RichFlapMaption，在里面读写hbase做业务逻辑，程序并没有用sink，然后直接提交就结束了，但是taskmanager一直起不来 java.lang.RuntimeException: Buffer pool is destroyed. at org.apache.flink.streaming.runtime.io.RecordWriterOutput.pushToRecordWriter(RecordWriterOutput.java:110) at org.apache.flink.streaming.runtime.io.RecordWriterOutput.collect(RecordWriterOutput.java:89) at org.apache.flink.streaming.runtime.io.RecordWriterOutput.collect(RecordWriterOutput.java:45) at org.apache.flink.streaming.api.operators.AbstractStreamOperator$CountingOutput.collect(AbstractStreamOperator.java:718) at org.apache.flink.streaming.api.operators.AbstractStreamOperator$CountingOutput.collect(AbstractStreamOperator.java:696) at org.apache.flink.streaming.api.operators.TimestampedCollector.collect(TimestampedCollector.java:51) at com.sprucetec.recommend.stream.manager.mapper.BusinessTypeMapper.flatMap(BusinessTypeMapper.java:56) at com.sprucetec.recommend.stream.manager.mapper.BusinessTypeMapper.flatMap(BusinessTypeMapper.java:24) at org.apache.flink.streaming.api.operators.StreamFlatMap.processElement(StreamFlatMap.java:50) at org.apache.flink.streaming.runtime.tasks.OperatorChain$CopyingChainingOutput.pushToOperator(OperatorChain.java:579) at org.apache.flink.streaming.runtime.tasks.OperatorChain$CopyingChainingOutput.collect(OperatorChain.java:554) at org.apache.flink.streaming.runtime.tasks.OperatorChain$CopyingChainingOutput.collect(OperatorChain.java:534) at org.apache.flink.streaming.api.operators.AbstractStreamOperator$CountingOutput.collect(AbstractStreamOperator.java:718) at org.apache.flink.streaming.api.operators.AbstractStreamOperator$CountingOutput.collect(AbstractStreamOperator.java:696) at org.apache.flink.streaming.api.operators.StreamSourceContexts$AutomaticWatermarkContext.processAndCollect(StreamSourceContexts.java:176) at org.apache.flink.streaming.api.operators.StreamSourceContexts$AutomaticWatermarkContext.processAndCollectWithTimestamp(StreamSourceContexts.java:194) 这个问题，各位有遇到不？ #Flink
