Re: question about balance info

there are multiple replicas for a block, we don't need to move a block from source - dest, just find a node with the block, and copy it to dest, then delete replica on the source. Why? We can choose a node which is closest to dest, or the source node is busy(too many blocks to move), make sense?

Re: Can not find hadoop packages

A homebrew user! You can rely on the hadoop script to generate a usable runtime and compile time classpath for you. So just do it as below (assuming 'hadoop' as a command is on your $PATH already): $ javac -cp $(hadoop classpath) -d myClasses WordCount.java On Thu, May 29, 2014 at 12:43 AM,

full partition handling

Google wasn’t helpful for this question: If a Hadoop cluster has multiple disk partitions assigned to HDFS and one of those partitions is full, how does HDFS react? TIA Brian

Re: full partition handling

Hi Brian, I'm not sure how it will react; I guess the datanode will report an error of no space left on device and fail to serve some requests trying to write on the partition that is full. To solve this issue, you have to manually move files from /dfs.datanode.data.dir//current to a

Re: full partition handling

There is no error reported as that specific partition will not be used for further write requests. In the configurations, you can specify multiple disk partitions for data node and even if any of that partition does not exists, it is simply skipped by hadoop. _Rahul On Thu, May 29, 2014 at 8:39

Re: ProcfsBasedProcessTree

Hi, The log messages mean ProcfsBasedProcessTree just updates internal information via procfs. The redundant log message is suppressed after 2.1.0-beta, 0.23.8. For more detail, please check YARN-476. Thanks, - Tsuyoshi On Wed, May 28, 2014 at 2:53 PM, Prashant Kommireddi prash1...@gmail.com
