Tsz Wo Nicholas Sze commented on HDFS-6133:
-------------------------------------------
- PBHelper.convert(..) only adds one FALSE when targetPinnings == null. Should
we add n FALSEs, where n = targetPinnings.length?
- Remove "use sticky bit" from the javadoc below since an implementation may
not use sticky bit.
{code}
//FsDatasetSpi
+ /**
+ * Use sticky bit to pin the block
+ */
+ public void setPinning(ExtendedBlock block) throws IOException;
{code}
- FileUtil currently does not support sticky bit so that using LocalFileSystem
is correct. Is there a way to add support to stick bit in FileUtil?
- There are some tab characters. Please replace them by spaces.
Thanks for working hard on this!

> If getBlocks could exclude blocks belongs to files which have specific path
> prefix, like "/hbase", then we can run Balancer without destroying
> Regionserver's data locality.
