Raju commented on HDFS-3731:
----------------------------
{quote}We should probably hook the "finalize" code to also rm -rf the
"blocksbeingwritten" directory, or else the storage will be leaked forever,
right?{quote}
Yes Todd forget to mention about finalize, we need to delete the BBW dir in
finalize
{quote}If you agree, may be we can file separate JIRA for that, as this JIRA
mainly talking about 2.0 upgrade from 1.0.
{quote}
Uma I accept your opinion but we need to modify the code which is already
released, I am not very clear on how to fix the same.
{quote}I thought that hardlinks to directories are not typically supported
...{quote}
Robert Here I am not directly referring to Hardlink like
{code}
ln sourceDir destDir
{code}
I am talking about using
{code}
void org.apache.hadoop.hdfs.server.datanode.DataStorage.linkBlocks(File from,
File to, int oldLV, HardLink hl)
{code}
which will do the individual file linking for all the blocks.
