> DataNode exceptions reading local disk
> --------------------------------------
>
> Key: HDFS-193
> URL: https://issues.apache.org/jira/browse/HDFS-193
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: sam rash
>
> We get 100s of exceptions at WARN level per day indicating errors while
> trying to read local blocks. When this occurs, I've checked on the local
> box's dfs.data.dir and the block is not present. Here is a relevant snippet
> from the logs regarding the missing block. It *looks* like the DataNode
> deletes the block and then tries to read it again later.
> NOTE: this is for the jar file as up to 8 hosts have this exception for one
> block and our data repl factor is only 3.
