testLockupAroundBadAssignSync

public void testLockupAroundBadAssignSync()
                                   throws IOException

Reproduce locking up that happens when we get an exceptions appending and syncing. See HBASE-14317. First I need to set up some mocks for Server and RegionServerServices. I also need to set up a dodgy WAL that will throw an exception when we go to append to it.

Throws:

IOException

initHRegion

public static org.apache.hadoop.hbase.regionserver.HRegion initHRegion(org.apache.hadoop.hbase.TableName tableName,
                                                                       byte[] startKey,
                                                                       byte[] stopKey,
                                                                       org.apache.hadoop.hbase.wal.WAL wal)

Returns:

A region on which you must call HBaseTestingUtility.closeRegionAndWAL(HRegion) when done.

Throws:

IOException
