Re: Intermittent No FileSystem found exception
I misspoke on the temporary workaround. Should use #withIgnoreWindowing() option on FileIO. On 10/25/19, 11:33 AM, "Maximilian Michels" wrote: Hi Maulik, Thanks for reporting.

Hi Maulik, I believe you may be witnessing this issue: https://issues.apache.org/jira/browse/BEAM-8303. We ran into this using beam-2.15.0 on flink-1.8 over S3.

Intermittent No FileSystem found exception
Hi everyone, We are running a Batch job on flink that reads data from GCS and does some aggregation on this data. We are intermittently getting issue: `No filesystem found for scheme gs` We are running Beam version 2.15.0 with FlinkRunner, Flink version: 1.6.4 On remote debugging the task managers, we found that in a few task managers, the *GcsFileSystemRegistrar is not added to the list of FileSystem Schemes*. In these task managers, we get this issue. The collection *SCHEME_TO_FILESYSTEM* is getting modified only in *setDefaultPipelineOptions* function call in org.apache.beam.sdk.io.FileSystems class and this function is not getting called and thus the GcsFileSystemRegistrar is not added to *SCHEME_TO_FILESYSTEM*. *Detailed stacktrace:* java.lang.IllegalArgumentException: No filesystem found for scheme gs at org.apache.beam.sdk.io.FileSystems.getFileSystemInternal(FileSystems.java:463) at org.apache.beam.sdk.io.FileSystems.matchNewResource(FileSystems.java:533) at org.apache.beam.sdk.io.fs.ResourceIdCoder.decode(ResourceIdCoder.java:49) at org.apache.beam.sdk.io.fs.MetadataCoder.decodeBuilder(MetadataCoder.java:62) at org.apache.beam.sdk.io.fs.MetadataCoder.decode(MetadataCoder.java:58) at org.apache.beam.sdk.io.fs.MetadataCoder.decode(MetadataCoder.java:36) at org.apache.beam.sdk.coders.Coder.decode(Coder.java:159) at org.apache.beam.sdk.coders.KvCoder.decode(KvCoder.java:82) at org.apache.beam.sdk.coders.KvCoder.decode(KvCoder.java:36) at org.apache.beam.sdk.util.WindowedValue$FullWindowedValueCoder.decode(WindowedValue.java:592) at org.apache.beam.sdk.util.WindowedValue$FullWindowedValueCoder.decode(WindowedValue.java:583) at org.apache.beam.sdk.util.WindowedValue$FullWindowedValueCoder.decode(WindowedValue.java:529) at org.apache.beam.runners.flink.translation.types.CoderTypeSerializer.deserialize(CoderTypeSerializer.java:92) at org.apache.flink.runtime.plugable.NonReusingDeserializationDelegate.read(NonReusingDeserializationDelegate.java:55) at org.apache.flink.runtime.io.network.api.serialization.SpillingAdaptiveSpanningRecordDeserializer.getNextRecord(SpillingAdaptiveSpanningRecordDeserializer.java:106) at org.apache.flink.runtime.io.network.api.reader.AbstractRecordReader.getNextRecord(AbstractRecordReader.java:72) at org.apache.flink.runtime.io.network.api.reader.MutableRecordReader.next(MutableRecordReader.java:47) at org.apache.flink.runtime.operators.util.ReaderIterator.next(ReaderIterator.java:73) at org.apache.flink.runtime.operators.NoOpDriver.run(NoOpDriver.java:94) at org.apache.flink.runtime.operators.BatchTask.run(BatchTask.java:503) at org.apache.flink.runtime.operators.BatchTask.invoke(BatchTask.java:368) at org.apache.flink.runtime.taskmanager.Task.run(Task.java:711) at java.lang.Thread.run(Thread.java:748) Inorder to resolve this issue, we tried calling the following in PTransform's expand function: FileSystems.setDefaultPipelineOptions(PipelineOptionsFactory.create()); This function call is to make sure that the GcsFileSystemRegistrar is added to the list, but this hasn't solved the issue.
