这个文件是确实不在了么？是不是被别的进程删掉了呢，可以通过hdfs的audit log来判断一下。
目前flink这边写文件的exactly once语义是依赖HDFS的一致性保证的，如果之前写到HDFS的数据丢掉了就会破坏这个语义了（不过我们可以考虑在这种情况下让作业能继续跑）。 On Tue, Aug 10, 2021 at 7:45 PM 周瑞 <[email protected]> wrote: > 您好：Flink > 写入Hive的时候，在压缩文件的时候有个待压缩的文件丢失了，导致Flink程序一直在不断重启，请问文件丢失是什么原因导致的，这种情况怎么能够让Flink程序正常启动 > 2021-08-10 19:34:19 java.io.UncheckedIOException: > java.io.FileNotFoundException: File does not exist: > hdfs://mycluster/user/hive/warehouse/test.db/offer_69/pt_dt=2021-8-10-72/.uncompacted-part-b2108114-b92b-4c37-b204-45f0150236f4-0-3 > at > org.apache.flink.table.filesystem.stream.compact.CompactCoordinator.lambda$coordinate$1(CompactCoordinator.java:163) > at > org.apache.flink.table.runtime.util.BinPacking.pack(BinPacking.java:38) > at > org.apache.flink.table.filesystem.stream.compact.CompactCoordinator.lambda$coordinate$2(CompactCoordinator.java:173) > at java.util.HashMap.forEach(HashMap.java:1288) at > org.apache.flink.table.filesystem.stream.compact.CompactCoordinator.coordinate(CompactCoordinator.java:169) > at > org.apache.flink.table.filesystem.stream.compact.CompactCoordinator.commitUpToCheckpoint(CompactCoordinator.java:151) > at > org.apache.flink.table.filesystem.stream.compact.CompactCoordinator.processElement(CompactCoordinator.java:141) > at > org.apache.flink.streaming.runtime.tasks.OneInputStreamTask$StreamTaskNetworkOutput.emitRecord(OneInputStreamTask.java:205) > at > org.apache.flink.streaming.runtime.io.AbstractStreamTaskNetworkInput.processElement(AbstractStreamTaskNetworkInput.java:134) > at > org.apache.flink.streaming.runtime.io.AbstractStreamTaskNetworkInput.emitNext(AbstractStreamTaskNetworkInput.java:105) > at > org.apache.flink.streaming.runtime.io.StreamOneInputProcessor.processInput(StreamOneInputProcessor.java:66) > at > org.apache.flink.streaming.runtime.tasks.StreamTask.processInput(StreamTask.java:423) > at > org.apache.flink.streaming.runtime.tasks.mailbox.MailboxProcessor.runMailboxLoop(MailboxProcessor.java:204) > at > org.apache.flink.streaming.runtime.tasks.StreamTask.runMailboxLoop(StreamTask.java:681) > at > org.apache.flink.streaming.runtime.tasks.StreamTask.executeInvoke(StreamTask.java:636) > at > org.apache.flink.streaming.runtime.tasks.StreamTask.runWithCleanUpOnFail(StreamTask.java:647) > at > org.apache.flink.streaming.runtime.tasks.StreamTask.invoke(StreamTask.java:620) > at org.apache.flink.runtime.taskmanager.Task.doRun(Task.java:779) > at org.apache.flink.runtime.taskmanager.Task.run(Task.java:566) at > java.lang.Thread.run(Thread.java:748) Caused by: > java.io.FileNotFoundException: File does not exist: > hdfs://mycluster/user/hive/warehouse/test.db/offer_69/pt_dt=2021-8-10-72/.uncompacted-part-b2108114-b92b-4c37-b204-45f0150236f4-0-3 > at > org.apache.hadoop.hdfs.DistributedFileSystem$29.doCall(DistributedFileSystem.java:1583) > at > org.apache.hadoop.hdfs.DistributedFileSystem$29.doCall(DistributedFileSystem.java:1576) > at > org.apache.hadoop.fs.FileSystemLinkResolver.resolve(FileSystemLinkResolver.java:81) > at > org.apache.hadoop.hdfs.DistributedFileSystem.getFileStatus(DistributedFileSystem.java:1591) > at > org.apache.flink.hive.shaded.fs.hdfs.HadoopFileSystem.getFileStatus(HadoopFileSystem.java:85) > at > org.apache.flink.table.filesystem.stream.compact.CompactCoordinator.lambda$coordinate$1(CompactCoordinator.java:161) > ... 19 more -- Best regards!
