Hello,
We're having a problem when calling HBaseAdmin.split() on an empty region. The new regions are never getting created and the RegionServer appears to be throwing an IllegalArgumentException with the following stack trace: java.lang.IllegalArgumentException at java.util.concurrent.ThreadPoolExecutor.<init>(ThreadPoolExecutor.java:589) at java.util.concurrent.ThreadPoolExecutor.<init>(ThreadPoolExecutor.java:514) 2631 at java.util.concurrent.Executors.newFixedThreadPool(Executors.java:84) 2632 at org.apache.hadoop.hbase.regionserver.SplitTransaction.splitStoreFiles(SplitTransaction.java:592) 2633 at org.apache.hadoop.hbase.regionserver.SplitTransaction.createDaughters(SplitTransaction.java:290) 2634 at org.apache.hadoop.hbase.regionserver.SplitTransaction.execute(SplitTransaction.java:452) 2635 at org.apache.hadoop.hbase.regionserver.SplitRequest.run(SplitRequest.java:67) 2636 at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) 2637 at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) 2638 at java.lang.Thread.run(Thread.java:680)
