I noticed that you're running on /. In general, this is a bad idea, as
space can disappear in various ways and you'll never know.

Hello, Edward,
I'm very glad to see this idea moving forward.
I'm not sure I get this.
1. If you format the filesystem (which I thought is usually executed on the
master node, but anyway)
don't you erase all your data?
2. I guess I need to add the new machine to the conf/slaves file,
but then I run the start-all.sh again from the master node while my cluster
Hi,
I have a dfs cluster with replication set to 3. In dfshealth.jsp, I see a node
with:
Size(GB) = 930.25
Used(%) = 9.83
Remaining(GB) = 631.08
How is this possible? Why doesn't (size - remaining = used * size)? Are Size
and Remaining measuring in different units (replicated vs. not)?

When starting hadoop, it stays in safe mode forever. Looking into the issue,
seems there is problem with block replication.
Command hadoop fsck / shows error msg:
/X/part-7.deflate: CORRUPT block blk_1402039344260425079
/X/part-7.deflate: MISSING 1 blocks of total size
http://markmail.org/message/2xtywnnppacywsya shows we can exit safe mode
explicitly and just delete these corrupted files.
But I don't know how to exit safe mode explicitly.

Hey Zheng,
You can explicitly exit safemode by
hadoop dfsadmin -safemode leave
Then, you can delete the file with the corrupt blocks by:
hadoop fsck / -delete
Joey: You may list the block locations for a specific file by:
hadoop fsck /user/brian/path/to/file -files -blocks
However, if they

You just start the new data-node as the cluster is running using
bin/hadoop datanode
The configuration on the new data-node should be the same as on other nodes.
The data-node should join the cluster automatically.
Formatting will destroy your file system.

It is really different from what you said that on my cluster, and
performing format command will not destroy the file system. And if I do
not perform format command on datanode, the datanode will not be able to
find my the master.
Hopefully anybody can tell me the reason.
