Hi folks, This looks like it sits in the intersection between HDFS and HBase. My region server logs are flooding with messages like "SecretManager$InvalidToken: access control error while attempting to set up short-circuit access to <hdfs-file-path> ... is expired" [0].
These logs correspond with responseTooSlow WARNings from the region server. Maybe I have misconfigured short-circuit reads? Such an expiration seems like something the client or client consumer should handle re-negotiations. Thanks a lot, -n [0] 2016-01-19 22:10:14,432 INFO [B.defaultRpcServer.handler=4,queue=1,port=16020] shortcircuit.ShortCircuitCache: ShortCircuitCache(0x71bdc547): could not load 1074037633_BP-1145309065-XXX-1448053136416 due to InvalidToken exception. org.apache.hadoop.security.token.SecretManager$InvalidToken: access control error while attempting to set up short-circuit access to <hfile path> token with block_token_identifier (expiryDate=1453194430724, keyId=1508822027, userId=hbase, blockPoolId=BP-1145309065-XXX-1448053136416, blockId=1074037633, access modes=[READ]) is expired. at org.apache.hadoop.hdfs.BlockReaderFactory.requestFileDescriptors(BlockReaderFactory.java:591) at org.apache.hadoop.hdfs.BlockReaderFactory.createShortCircuitReplicaInfo(BlockReaderFactory.java:490) at org.apache.hadoop.hdfs.shortcircuit.ShortCircuitCache.create(ShortCircuitCache.java:782) at org.apache.hadoop.hdfs.shortcircuit.ShortCircuitCache.fetchOrCreate(ShortCircuitCache.java:716) at org.apache.hadoop.hdfs.BlockReaderFactory.getBlockReaderLocal(BlockReaderFactory.java:422) at org.apache.hadoop.hdfs.BlockReaderFactory.build(BlockReaderFactory.java:333) at org.apache.hadoop.hdfs.DFSInputStream.blockSeekTo(DFSInputStream.java:618) at org.apache.hadoop.hdfs.DFSInputStream.readWithStrategy(DFSInputStream.java:844) at org.apache.hadoop.hdfs.DFSInputStream.read(DFSInputStream.java:896) at java.io.DataInputStream.read(DataInputStream.java:149) at org.apache.hadoop.hbase.io.hfile.HFileBlock.readWithExtra(HFileBlock.java:678) at org.apache.hadoop.hbase.io.hfile.HFileBlock$AbstractFSReader.readAtOffset(HFileBlock.java:1372) at org.apache.hadoop.hbase.io.hfile.HFileBlock$FSReaderImpl.readBlockDataInternal(HFileBlock.java:1591) at org.apache.hadoop.hbase.io.hfile.HFileBlock$FSReaderImpl.readBlockData(HFileBlock.java:1470) at org.apache.hadoop.hbase.io.hfile.HFileReaderV2.readBlock(HFileReaderV2.java:437) at org.apache.hadoop.hbase.io.hfile.HFileBlockIndex$BlockIndexReader.loadDataBlockWithScanInfo(HFileBlockIndex.java:259) at org.apache.hadoop.hbase.io.hfile.HFileReaderV2$AbstractScannerV2.seekTo(HFileReaderV2.java:634) at org.apache.hadoop.hbase.io.hfile.HFileReaderV2$AbstractScannerV2.reseekTo(HFileReaderV2.java:614) at org.apache.hadoop.hbase.regionserver.StoreFileScanner.reseekAtOrAfter(StoreFileScanner.java:267) at org.apache.hadoop.hbase.regionserver.StoreFileScanner.reseek(StoreFileScanner.java:181) at org.apache.hadoop.hbase.regionserver.NonLazyKeyValueScanner.doRealSeek(NonLazyKeyValueScanner.java:55) at org.apache.hadoop.hbase.regionserver.KeyValueHeap.generalizedSeek(KeyValueHeap.java:312) at org.apache.hadoop.hbase.regionserver.KeyValueHeap.reseek(KeyValueHeap.java:256) at org.apache.hadoop.hbase.regionserver.StoreScanner.reseek(StoreScanner.java:817) at org.apache.hadoop.hbase.regionserver.StoreScanner.seekToNextRow(StoreScanner.java:792) at org.apache.hadoop.hbase.regionserver.StoreScanner.next(StoreScanner.java:621) at org.apache.hadoop.hbase.regionserver.KeyValueHeap.next(KeyValueHeap.java:147) at org.apache.hadoop.hbase.regionserver.HRegion$RegionScannerImpl.populateResult(HRegion.java:5486) at org.apache.hadoop.hbase.regionserver.HRegion$RegionScannerImpl.nextInternal(HRegion.java:5637) at org.apache.hadoop.hbase.regionserver.HRegion$RegionScannerImpl.nextRaw(HRegion.java:5424) at org.apache.hadoop.hbase.regionserver.HRegion$RegionScannerImpl.nextRaw(HRegion.java:5410) at org.apache.phoenix.coprocessor.GroupedAggregateRegionObserver$1.next(GroupedAggregateRegionObserver.java:510) at org.apache.phoenix.coprocessor.BaseRegionScanner.next(BaseRegionScanner.java:40) at org.apache.phoenix.coprocessor.BaseRegionScanner.nextRaw(BaseRegionScanner.java:60) at org.apache.phoenix.coprocessor.DelegateRegionScanner.nextRaw(DelegateRegionScanner.java:77) at org.apache.hadoop.hbase.regionserver.RSRpcServices.scan(RSRpcServices.java:2395) at org.apache.hadoop.hbase.protobuf.generated.ClientProtos$ClientService$2.callBlockingMethod(ClientProtos.java:32205) at org.apache.hadoop.hbase.ipc.RpcServer.call(RpcServer.java:2114) at org.apache.hadoop.hbase.ipc.CallRunner.run(CallRunner.java:101) at org.apache.hadoop.hbase.ipc.RpcExecutor.consumerLoop(RpcExecutor.java:130) at org.apache.hadoop.hbase.ipc.RpcExecutor$1.run(RpcExecutor.java:107) at java.lang.Thread.run(Thread.java:745)
