the version is hbase0.98.10, find some improvements on snapshot:
1. in class SnapshotManager, line 725, we make a clone of HTableDescriptor,
the clone is not so need to make
2 class HBaseAdmin, method
public void restoreSnapshot(final String snapshotName, boolean
takeFailSafeSnapshot)
{
TableName tableName = null;
for (SnapshotDescription snapshotInfo: listSnapshots()) {
if (snapshotInfo.getName().equals(snapshotName)) {
tableName = TableName.valueOf(snapshotInfo.getTable());
break;
}
}
......
}
must get all snapshot from master and then get the one we need, can improve
this, master just return the snapshot client needed
3. there should better has a method 'isSnapShotExists' in HBaseAdmin
