Konstantin Shvachko commented on HADOOP-2549:
---------------------------------------------
Yes, that should turn on volume switching if one of them is full.
Some comments.
- It is better to move declaration of estimateBlockSize up together with all
other member declarations
- Use JavaDoc style comment for estimateBlockSize instead of the regular ones.
That way I can see the description whenever I move the cursor over the variable
in Eclipse.
- Do we plan to apply it to previous releases 0.14 or 0.15? If not then could
you please also remove unused pieces of code
-# import org.apache.hadoop.io.Text;
-# private void enumerateThreadGroup()
-# short opStatus
> hdfs does not honor dfs.du.reserved setting

> running 0.14.4. one of our drives is smaller and is always getting disk full.
> i reset the disk reservation to 1Gig - but it was filled quickly again.
> i put in some tracing in getnextvolume. the blocksize argument is 0. so every
> volume (regardless of available space) qualifies. here's the trace:
> /* root disk chosen with 0 available bytes. format is
> <available>:<blocksize>*/
> 2008-01-08 08:08:51,918 WARN org.apache.hadoop.dfs.DataNode: Volume
> /var/hadoop/tmp/dfs/data/current:0:0
> /* some other disk chosen with 300G space. */
> 2008-01-08 08:09:21,974 WARN org.apache.hadoop.dfs.DataNode: Volume
> /mnt/d1/hdfs/current:304725631026:0
> i am going to default blocksize to something reasonable when it's zero for
> now.
> this is driving us nuts since our automounter starts failing when we run out
> of space. so everything's broke.
