org.apache.hadoop.hbase.MultithreadedTestUtil.TestThread

org.apache.hadoop.hbase.MultithreadedTestUtil.RepeatingTestThread

org.apache.hadoop.hbase.regionserver.TestHRegionServerBulkLoad.AtomicHFileLoader

All Implemented Interfaces:

java.lang.Runnable

Enclosing class:

TestHRegionServerBulkLoad

public static class TestHRegionServerBulkLoad.AtomicHFileLoader
extends MultithreadedTestUtil.RepeatingTestThread

Thread that does full scans of the table looking for any partially completed rows. Each iteration of this loads 10 hdfs files, which occupies 5 file open file handles. So every 10 iterations (500 file handles) it does a region compaction to reduce the number of open file handles.
