Description
I left a Datanode running overnight and found this in the logs in the morning:
2017-10-18 23:51:54,391 ERROR datanode.DirectoryScanner: Error compiling report for the volume, StorageId: DS-e75ebc3c-6b12-424e-875a-a4ae1a4dcc29 java.util.concurrent.ExecutionException: java.lang.IllegalArgumentException: URI scheme is not "file" at java.util.concurrent.FutureTask.report(FutureTask.java:122) at java.util.concurrent.FutureTask.get(FutureTask.java:192) at org.apache.hadoop.hdfs.server.datanode.DirectoryScanner.getDiskReport(DirectoryScanner.java:544) at org.apache.hadoop.hdfs.server.datanode.DirectoryScanner.scan(DirectoryScanner.java:393) at org.apache.hadoop.hdfs.server.datanode.DirectoryScanner.reconcile(DirectoryScanner.java:375) at org.apache.hadoop.hdfs.server.datanode.DirectoryScanner.run(DirectoryScanner.java:320) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:308) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$301(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:294) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) Caused by: java.lang.IllegalArgumentException: URI scheme is not "file" at java.io.File.<init>(File.java:421) at org.apache.hadoop.hdfs.server.datanode.fsdataset.FsVolumeSpi$ScanInfo.<init>(FsVolumeSpi.java:319) at org.apache.hadoop.hdfs.server.datanode.fsdataset.impl.ProvidedVolumeImpl$ProvidedBlockPoolSlice.compileReport(ProvidedVolumeImpl.java:155) at org.apache.hadoop.hdfs.server.datanode.fsdataset.impl.ProvidedVolumeImpl.compileReport(ProvidedVolumeImpl.java:493) at org.apache.hadoop.hdfs.server.datanode.DirectoryScanner$ReportCompiler.call(DirectoryScanner.java:620) at org.apache.hadoop.hdfs.server.datanode.DirectoryScanner$ReportCompiler.call(DirectoryScanner.java:581) at java.util.concurrent.FutureTask.run(FutureTask.java:266) ... 3 more
The code in question tries to make a File from the URI (in this case s3a but anything in Provided storage would likely break here:
public ScanInfo(long blockId, File blockFile, File metaFile,
FsVolumeSpi vol, FileRegion fileRegion, long length) {
this.blockId = blockId;
String condensedVolPath =
(vol == null || vol.getBaseURI() == null) ? null :
getCondensedPath(new File(vol.getBaseURI()).getAbsolutePath()); // <-------
this.blockSuffix = blockFile == null ? null :
getSuffix(blockFile, condensedVolPath);
this.blockLength = length;
if (metaFile == null) {
this.metaSuffix = null;
} else if (blockFile == null) {
this.metaSuffix = getSuffix(metaFile, condensedVolPath);
} else {
this.metaSuffix = getSuffix(metaFile,
condensedVolPath + blockSuffix);
}
this.volume = vol;
this.fileRegion = fileRegion;
}
