Problem reported by Brahma Reddy. > The {{DataNode}} will only have one block pool after upgrading from a 1.x > release. (This is because in the 1.x releases, there were no block pools-- > or equivalently, everything was in the same block pool). During the upgrade, > we should hardlink the block files from the {{blocksBeingWritten}} directory > into the {{rbw}} directory of this block pool. Similarly, on {{-finalize}}, > we should delete the {{blocksBeingWritten}} directory. -- This message is automatically generated by JIRA.
