I'm not sure though if the natural splits are safe - they seem to be, but I need to test that too. RegionSplitPolicy.getSplitPoint() calls Store.getSplitPoint() Store.getSplitPoint seems to do the check. {code} for (StoreFile sf : storefiles) { if (sf.isReference()) { // Should already be enforced since we return false in this case assert false : getSplitPoint() called on a region that can't split!; return null; } {code} BTW, we also have Store.hasReferences() {code} private boolean hasReferences(CollectionStoreFile files) { if (files != null files.size() 0) { for (StoreFile hsf: files) { if (hsf.isReference()) { return true; } } } return false; } {code} However here's the code in HRegion.checkSplit() If there's an explicit split point it won't get to do the reference check. {code} public byte[] checkSplit() { // Can't split META if (getRegionInfo().isMetaRegion()) { if (shouldForceSplit()) { LOG.warn(Cannot split meta regions in HBase 0.20 and above); } return null; } if (this.explicitSplitPoint != null) { return this.explicitSplitPoint; } if (!splitPolicy.shouldSplit()) { return null; } byte[] ret = splitPolicy.getSplitPoint(); if (ret != null) { try { checkRow(ret, calculated split); } catch (IOException e) { LOG.error(Ignoring invalid split, e); return null; } } return ret; } {code} Multiple return points + a ret variable - this could use some polishing too :) I'm a bit puzzled about the natural split, because, I've seen the problem with a forced split from UI where I don't think we provide an explicit split point.

The regionserver doing the split dies and the master will get into an infinite loop trying to assign regions that seem to have the files missing from HDFS. The table can be disabled once. upon trying to re-enable it, it will remain in an intermediary state forever. I was able to reproduce this on a smaller table consistently. {code} hbase(main):030:0 (0..1).each{|x| put 't1', #{x}, 'f1:t', 'dd'} hbase(main):030:0 (0..1000).each{|x| split 't1', #{x*10}} {code} Running overlapping splits in parallel (e.g. #{x*10+1}, #{x*10+2}... ) will reproduce the issue almost instantly and consistently. {code} 2012-03-28 10:57:16,320 INFO org.apache.hadoop.hbase.catalog.MetaEditor: Offlined parent region t1,,1332957435767.2fb0473f4e71339e88dab0ee0d4dffa1. in META 2012-03-28 10:57:16,321 DEBUG org.apache.hadoop.hbase.regionserver.CompactSplitThread: Split requested for t1,5,1332957435767.648d30de55a5cec6fc2f56dcb3c7eee1.. compaction_queue=(0:1), split_queue=10 2012-03-28 10:57:16,343 INFO org.apache.hadoop.hbase.regionserver.SplitRequest: Running rollback/cleanup of failed split of t1,,1332957435767.2fb0473f4e71339e88dab0ee0d4dffa1.; Failed ld2,60020,1332957343833-daughterOpener=2469c5650ea2aeed631eb85d3cdc3124 java.io.IOException: Failed ld2,60020,1332957343833-daughterOpener=2469c5650ea2aeed631eb85d3cdc3124 at org.apache.hadoop.hbase.regionserver.SplitTransaction.openDaughters(SplitTransaction.java:363) at org.apache.hadoop.hbase.regionserver.SplitTransaction.execute(SplitTransaction.java:451) at org.apache.hadoop.hbase.regionserver.SplitRequest.run(SplitRequest.java:67) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) Caused by: java.io.FileNotFoundException: File does not exist: /hbase/t1/589c44cabba419c6ad8c9b427e5894e3.2fb0473f4e71339e88dab0ee0d4dffa1/f1/d62a852c25ad44e09518e102ca557237 at org.apache.hadoop.hdfs.DFSClient$DFSInputStream.openInfo(DFSClient.java:1822) at org.apache.hadoop.hdfs.DFSClient$DFSInputStream.init(DFSClient.java:1813) at org.apache.hadoop.hdfs.DFSClient.open(DFSClient.java:544) at org.apache.hadoop.hdfs.DistributedFileSystem.open(DistributedFileSystem.java:187) at org.apache.hadoop.fs.FileSystem.open(FileSystem.java:456) at org.apache.hadoop.hbase.io.hfile.HFile.createReader(HFile.java:341) at org.apache.hadoop.hbase.regionserver.StoreFile$Reader.init(StoreFile.java:1008) at org.apache.hadoop.hbase.io.HalfStoreFileReader.init(HalfStoreFileReader.java:65) at org.apache.hadoop.hbase.regionserver.StoreFile.open(StoreFile.java:467) at org.apache.hadoop.hbase.regionserver.StoreFile.createReader(StoreFile.java:548) at org.apache.hadoop.hbase.regionserver.Store.loadStoreFiles(Store.java:284) at org.apache.hadoop.hbase.regionserver.Store.init(Store.java:221) at org.apache.hadoop.hbase.regionserver.HRegion.instantiateHStore(HRegion.java:2511) at org.apache.hadoop.hbase.regionserver.HRegion.initialize(HRegion.java:450) at org.apache.hadoop.hbase.regionserver.HRegion.openHRegion(HRegion.java:3229) at org.apache.hadoop.hbase.regionserver.SplitTransaction.openDaughterRegion(SplitTransaction.java:504) at org.apache.hadoop.hbase.regionserver.SplitTransaction$DaughterOpener.run(SplitTransaction.java:484) ... 1 more 2012-03-28 10:57:16,345 FATAL org.apache.hadoop.hbase.regionserver.HRegionServer: ABORTING region server ld2,60020,1332957343833: Abort; we got an error after point-of-no-return {code} http://hastebin.com/diqinibajo.avrasm later edit: (I'm using the last 4 characters from each string) Region 94e3 has storefile 7237 Region 94e3 gets splited in daughters a: ffa1 and b: eee1 Daughter region ffa1 get's splitted in daughters a: 3124 and b: dc77
