---------------------------------------------
Summary: IlegalArgument Exception is thrown when an empty region
is spliitted.
Key: HBASE-6853
URL: https://issues.apache.org/jira/browse/HBASE-6853
Project: HBase
Issue Type: Bug
Affects Versions: 0.94.1, 0.92.1
Reporter: ramkrishna.s.vasudevan
This is w.r.t a mail sent in the dev mail list.
Empty region split should be handled gracefully. Either we should not allow
the split to happen if we know that the region is empty or we should allow the
split to happen by setting the no of threads to the thread pool executor as 1.
{code}
int nbFiles = hstoreFilesToSplit.size();
ThreadFactoryBuilder builder = new ThreadFactoryBuilder();
builder.setNameFormat("StoreFileSplitter-%1$d");
ThreadFactory factory = builder.build();
ThreadPoolExecutor threadPool =
(ThreadPoolExecutor) Executors.newFixedThreadPool(nbFiles, factory);
List<Future<Void>> futures = new ArrayList<Future<Void>>(nbFiles);
{code}
Here the nbFiles needs to be a non zero positive value.
